- Опубликовано: 7 сен 2024
- www.cemetech.n... || In 2011, Casio took the graphing calculator by storm with the first true color-screen graphing calculator, the Casio Prizm. Now, they have introduced a successor to the fx-CG10/fx-CG20, a sleek new calculator called the fx-CG50. Does it have what it takes to beat the TI-84 Plus CE and improve on the older Prizm? Find out with this hands-on exploration.
Quarantine really got me watching videos bout calculators
Cepha good thing to be doing with your time!

I hope they keep using normal batteries. If they start using rechargeble batteries, one day they'll have not much time of use. Replaceable batteries, we can just replace, so I think it's better, even if the calculator is thicker than TI's calculators. Amazing website and video, btw! Keep up the amazing work!
I've got to say the winner for me is that fact that it has replaceable batteries. I am still able to use my original fx-7000g from the 1980s whereas if it had an internal battery would have been rendered useless years ago.
I had no idea we had the technology in the 1980's to even make a small hand-held graphing calculator. Thank you for the info. Were you in high school or college when you bought it? I bet every kid your class drooled over it.
Great overview of the calculator and thanks for posting. I am an older engineer using the CG50 and I appreciate the size of the fonts and the backlit screen which is very easy to read. The calculator is adept at doing mixed complex number calculations meaning that one have both polar and rectangular complex numbers in the same calculation which makes AC circuit calcs a breeze. CASIO has done a fine job of continuing development of calculators in the very one-sided marketplace and allowed us to have choices. Imagine a world with nothing but TI calculators...
I don´t care if it fells lighter and thinner what matters is being able to quickly be able to switch the batteries if in the morning just before the test I found out that I forgot to put the calc to charge the night before, and still can use rechargeables AA batteries
I'm really shocked how many people care more about the batteries being swappable than about other features of the device. This is helpful, though! Thanks for the feedback.
Proprietary batteries are discontinued = device becomes useless. What's the point in spending a considerable sum of money on such a calculator? AA/AAA batteries are the way to go, and reassures me that the company isn't trying to rip me off.
Yup, get some rechargeable AAA batteries to save money, but if it dies you're not tethered to the wall or waiting. Just use cheap alkaline.
In the graphing function, the Casio CG50 does a lot better than the Ti 84 Plus Ce because of the many options available. For example, to convert between graphs of equations, inequalities... Casio has an option available right in the graphing function while Ti 84 Plus CE has to install an external APP which is very inconvenient and lacks many options.
Try drawing a 2D graph of the quadratic function with 2 roots and calculate the integral from the 2 roots of the equation right on the graph. Ti 84 Plus Ce does not have the option to choose the lower and upper bound from the roots of the equation or the intersection of the graphs, but must do it manually. The Casio CG50 has that option and is fully automatic so it's fast and intuitive.
I actually like AAA batteries. I find them overall more convenient (I just have rechargeable ones)
That's certainly a good compromise. I continue to be flabbergasted at just how many people picked up on standard AAAs as the particular feature to prefer.
@@KermMartian I have an HP 65 calculator I used in the 1970s. It has a rechargeable nicad battery pack that is really hard to replace. I can only use it if it is plugged in. If it had used AAA batteries, this would not be a problem. For longevity, the AAA option is preferable for many people.
I actually like the (Ni-MH) AAA batteries. I don't have to throw away my calculators or make modifications that could make the original unit ugly. Also, I bought the TI Nspire when it came out because it is powered by AAA batteries, and didnn't buy the CX version because of the lithium battery even though it has a color screen.
I love all of my calculators. Thank you for this vid. I almost bought the old casio. I have the Nspire cas, 84 plus CE, HP prime. This and the CG500 are the ones missing from my collection :P. For now at least. I have no games on them. I just appreciate the math and physics functions (even if I have to program them :) ) Very helpful!
Thanks for that! If you feel like weighing in, I'd appreciate your feedback on which of those you like the most and why in this thread: www.cemetech.net/news.php?id=863
I sent you a message on cemetech/facebook. If you have time, read it :)
I was surprised when my kid came home saying she needed a graphing calculator for school. The only 'book' she has is chemistry class, the rest of her text books are software versions in her laptop. I would have assumed that graphing would be done via some cloud app either on her laptop or phone. Thanks for the review. Since she will be using the calculator on the SAT, I'm reviewing RUclips videos to research what might be the best for her and will forward this video to her to review as she ultimately will make the decision on the one she will get.
Nice round up here, though honestly, i don't see tripple a's as being a negative unless you are forced to use non alkalines for some reason, the slim and light form factor is purely aesthetic in 99% of cases most pockets are designed to take a smartphone in a case, a wallet and or keys at this point and that's within the ballpark size we have here, what i do see is that the casio will have the advantage that you can pop into any local shop and grab some fresh cells where as if the battery in the ti pops just like with a smartphone or laptop you're in a world of hurt. if you are that concerned about your calculator power there are numerous usb power-bank and similar devices that you could hook up to the battery door to power it for probably longer than you'll need it.. that said, we can almost get micro laptops this small these days so i feel the days of pocket calculators are going away anyway, personally i was looking to see what can be done with these devices in the "smart" age and the answer looks a tad depressing really.
The updated firmware version OS 3.10 is out now, along with an updated 3D Graph application version 1.01. It's probably worthy of a follow-up video, as the 3D graphing app now has more general 3D graphing capabilities.
Great idea; I'll do so when I get a chance! Thanks for the suggestion.
I recently found and powered-up my college HP 48GX that had been sitting for roughly 25 years. Any issues? Nope, because it took standard AAA batteries. I'd like to upgrade to the HP Prime G2. The G2 uses a replaceable cell phone battery, the same one used in the Samsung Galaxy S III. Problem, the S III is long gone and so are the quality batteries for it. You could take a chance on a generic Chinese brand of unknown quality, but do you really want to do that with something that could burst and catch fire? AAA is the way.
Would like to see the new Casio compared to the Prime. Please include HP Prime in future comparisons (both +/-). Thanks.
Great idea; will do! Thank you.
I'll do my best, thanks!
Being able to use triple AAA batteries is a feature and not a bug. I am using rechargable NiMH batteries with the Casio FX-CG50. Batteries in this sense is then not proprietary as with those with in-built rechargeable batteries. It is more versatile and if the calculator goes low in power when we are outside ? Just pop in a set of fresh batteries and we are good to go !
CG-50 would be lovely. I actually think the standard batteries are an advantage. I'd like to know, can modern casios handle string/character manipulation when programming?
yes , casio calculators support string manipulation.
By the way, is it (on the fx-CG50) possible the use of units in the "equation solver" app like on the HP 48G series calculator from Hewlett Packard?
On the HP 48G series, when using the "equation solver" you can use units even in different system and get the solution of the variable you want. For example:
Volume of cylinder (I work with diameters rather than radius):
π × (d/2)^2 × h = V
d = 6_in
h = 1500_m
V = (solve)_bbl
With the HP 48G series, you can add units (even in different system) to each parameter. For instance you enter 6 inches (6_in) for the diameter, 1500 meters (1500_m) for the height and you want to get the volume in barrels, so you write whatever value in barrels (1_bbl). Then you press "SOLVE" on the volume and the calculator gives you the volume of the cylinder in barrels. Should you want for instance the diameter in meters instead of inches, then you write it in meters (6_m), or the volume in cubic meters or cubic feet then write the unit accordingly (1_m3 or 1_ft3). And so on. You can use any type of unit.
Is it possible the use of units on the Casio fx-CG50 in the "equation solver" like you can do on the HP 48G series?
I got cg50 it’s awesome
9:00 you Can draw Custom functions in 3D Graph . Choose: "TYPE" > "Z=" > write your function > "SET" (I'm using firmware version 3.80)
But, can it run doom?
it can
Yeah i have doom 2.43mb and pokemon red 6.86mb
Can the fxcg50 run doom, if so, pls post a download link
@@fistandboot6598 how the heck is ur pokemon game that big, mine is only around 1 mb
@@YachtyBurner I have both Pokemon gold and yellow, they are 2mb and 1mb respectively
My plea to Casio is we need a new Calculator to replace CG50 with significant feature improvements and refinements with both software and hardware upgrades.
Your graphing app is so cool, I downloaded it recently on my cg50 and it rotates graphs super fast. but it lacks a few things like parametric graphing.
@@lazermonarch2555It's there on his video discription friend 🙂.
I can tell this guy is legit buy how worn out his calculator is lol. Also I like replaceable batteries, you can use NiMh and still recharge them and gives you lots more options without worrying about battery wear over time.
Made a short list of items I would like to see on the next version of CG50:
Show the derivative in X or Y solver, not just in trace in the graph mode.
Provide dy/dx solver in graphing app so that x/y value can be found for a given gradient... and also for a given second derivative.
Provide a gsolve option to identify points of inflections in the graph. And even identify concave and convex areas in different colour.
Allow parametric equation solve features just like normal cartesian graph gsolve features as none of the g solve soft keys work at the moment when it comes to parametrically defined curves. Allow us to do everything including finding areas.
Please move the radian degrees item to first on the list of settings as we have to frequently switch between degrees or radians and it requires too many key strokes.
We can find the tangent/normal to a graph using sketch option but the equation of the tangent/normal cannot be pasted into the graphing app as a curve. If we could than it would be easier to find where the normal/tangent intersects other key points.
Please allow us to adjust the font size.
The bottom keys of the CG50 have been shaven off at an angle compared to the Classwiz 991EX. The height of the area we press is less. This makes key presses less comfortable than classwiz 991EX. Please could you restore full size.
Allow recurring decimals option where we can enter and convert between recurring decimals and other formats.
Allow us to find prime factors of a number, as other less advanced Casio's do.
Allow calculations of volumes of revolution, and 3D depiction of volumes of revolutions.
Conics app is isolated from graph app and is really not that useful... we need to be able to plot tangents or other curves with the circles to find intersections with the circle etc.
Importantly, please could you allow us to define a cartesian graphs IMPLICITLY... the grapher becomes useless when an equation is implicitly defines. Other calculators are able to show implicit graphs. This allow circles to be plotted easily without a separate conics app.
The new distribution app is almost useless in an exam conditions or computations setting. This is because it lacks all the features for calculating but visually shows the distribution (useful), which means you need to be in the stats app for calculations. So to make the ability to see the distribution accessible, I would like the option to visually see my distributions where I am doing my calculations (stats ap) and not have an isolated distribution app to go to. Please integrate the distribution ap features in the stats app. Infact, the z distribution shows in the stats ap. Please integrate the distributions app this way.
When we get an answer for a probability in the stats ap, please allow us to copy / store in a variable like x/ANS so we can move to main and use that value for the probability in a calculation... often we have to remember a string of digits to copy.
Transformation of 3D images in geometry app will be very useful.
Please allow us to copy the ANSWERS from intermediate calculations in main rather then just the calculations line... this is a really annoying omission from the calculator.
Also sometimes calculations line that used ANS in the calculation does not contain the answer from the part before if further calculations were executed...a software method to detect this would be nice where it takes the answer from the line before.
Enable Spearman’s rank correlation coefficient calculations in the stats ap.
Allow access to all Statistical Table of values (eg. Critical values) for all types of distribution such as for critical values for Hypothesis testing for zero correlation of bivariate data - PMCC values vs significance level and sample size. Allow us to access stats data as we still have to use a book to access these stats data, it should be in CG50, if it has a periodic table it should have this.
Allow the stats app to perform Hypothesis testing for different distributions by taking all the required parameters (like numworks calculator does).
Allow Negative binomial distribution function in the statistics aps.
Recursion web graph does not start at the table start, please fix this.
List commands have to be executed in main rather that in the stats app making it difficult for use.
Again, please bring the ANS key to CG50 like the classwiz.
Square root should also ideally be a direct key and not a shift operation.
When we select a function operation using soft keys in main and it appears on the screen, knowing the syntax is often a problem, find a way to quickly view the syntax of the operation.
Some of the vector operations and vector input are in different locations, bring them in a coherent place.
Provide decametres and decimetres for length conversion.
A dark mode option.
Can you do a video on how to write a subroutine and call it on the cg50? Maybe like a subroutine called sphere which calculates the volume of the sphere, v=4/3pi(r)cubed. I found a subroutine like this on the internet, but it would not run on the fx cg50. It was written for an earlier Casio calculator.
So, I have my CG-50, and love everything about it....
but I have a question about the ports...
what is the port on the right of the USB port?
It's a serial I/O port, used for communicating with both other Prizms and older calculators. It's physically compatible but electrically incompatible with the similar I/O port on TI calculators.
Thank You!
do you recommend it for college math?
I hate these proprietary LiPo accumulators, i don't want to order them from nowhere when calculator become unsupported by producer. It is planned obsolence, buy new model or u will not get our special accumulators. Instead AAA are standard and work for years, just buy new rechargeable AAA and use r calc another 100 years :-) CASIO behave quite wise in this case !
wait. for the Casio CG50 you can buy 4 rechargable batteries AAA for a few bucks. they do not only work perfectly, but the calculator has got an USB chargingport at the top. So you even don't have to change the batteries. just plug in the usb charger and wait a while, The Screen is AWESOME I love it you can read it from any possible ankle muh better than my old backlit fx-9860GII
Without looking it up, I'd say the USB is for comms only. Different batteries have different voltages and metals inside and make for charging difficulties.
I belive it would be possible to mod a baterry to the fx-Cg50, I don't see why it wouldnt be possible and it would possible be able to use the micro USB to charge it with just a simple extra small board and add some cables.
The only problem is that the system may not detect the percentage of the battery.
I will need to do some test to be 100% confident about this comment.
Definitely possible. Please share on cemetech.net if you try this!
There are many Colour-Screen graphing calculator in the app store for iPhone like HP Prime graphing calculator, good speed drawing 3D.
That's true, but many students aren't allowed to use their phones in the classroom or especially on tests, and many professionals also prefer a physical, purpose-built device over pulling up an app.
Not having standard batteries is a huge Con, I have an HP 48g from almost 20 years ago and still works beautyfully, if it had proprietary batteries it would be in the trash now. And all my casios are still working. If i buy an expensive product i expect it to have it working for decades. The Ti-84 ce wont be working in 7 years. Not acceptable.
Being Spanish together with English the two most important languages in the world, I wonder why the rear side of the package of this calculator (Casio fx-CG50) is written in several languages except in Spanish.
Casio fx-cg50 is the best non cas graphing calculator. Text and screen are too small on ti.
The fx-CG50 is fantastic though I'm die hard TI, though, I wish there was a better following & documentation for the Casio calcs.
Hi, I’m an Italian Student and for our official exams (the grade of those are super important and they are going to be the only thing that matters about our high school), we can use only certain type of graphic calculator. The Casio Fx-cg50, is one of them. Do u actually think buying one is worth it or not?
2:20 The functions referred to here set the default for all NEW graphs. To change an EXISTING graph, one has to use the Convert functions. Admittedly this a confusing design.
forget you

This video is A-W-E-S-O-M-E!!! Thanks man!!
Thanks for the positive feedback; glad to help!
is there another casio cg50 version able to graph two variable functions like z=x+y ?
Do you know how long the battery lasts for the fx-cg50 compared to the fx-cg20?
Is it possible on some of those calculators to do double or triple integrals by graphing or simply mathematically? Thanks in advance!
Anyway, very good video, nice demonstration, nice explanations also!
IMO, 4 AAA batteries is better than rechargeable, say 20 years later, it is easier to get AAA batteries than rechargeable battery, AAA batteries survive a long time till now and probably into the future. But rechargeable battery specific for this calculator may not be manufactured sometimes in the future. Also, if the calculator is not being used, take out the batteries and store it away, will be vintage 20,30 years from now. Lastly, NiMH batteries can be used as well, just have to take them out to charge. 5 years later, Casio still do not have a replacement (non CAS calculator) for fx-CG50.
It continues to be fascinating to me just how many people say this. I have incorporated this viewpoint/advice into my latest back to School calculator guide, since it's so widespread.
Bonjou sitwayen! Ou ta dwe prezante anpil enfòmasyon background ak premye plan sou fx-9860GIII la. Apre sa, nan yon videyo SEPA, telechaje yon videyo sou diferansyasyon ak konparezon ak fx-CG50 AK fx-9860GIII. Mwen definitivman ta renmen konnen kiyès ki pi bon an. Mwen gen opinyon mwen. Mwen jis vle wè li nan men “ou”.
Is this useful for Electrical Engineering work?
Actually i ONLY buy Casio graphics calculators BECAUSE they use AAA batteries. Benefits i can find them everywhere, i can change them at any time when my device runs down. And most importantly they are not proprietary. And also you can use rechargeables. Thank you CASIO
Is there a way you can input your own 3d graphs to be drawn, not just by using the templates?
Yes! You can use my Graph3DP on your Prizm: www.cemetech.net/programs/index.php?mode=file&id=727
Okay thank you very much! :)
integral and differential equations how do u make them in this calculators?
have you found any programs for the prizm that dont work on the cg50?

@@arshaqhabib1932 Thanks!
Hello, i have a doubt in ti 84 plus ce, the calculator shows calculs ,for example, cos(30º)=square root of three over two or only in numeral?
Only in decimals. People have made TI-BASIC programs that can simplify radicals or produce radical/fraction answers from decimals, but it's not something built into the calculator.
Thnk you sir. Actually i wanna know that what's the best calculator for statistics?
Are there any python files, I can put on my Fx CG50 form cemetech
hi, it seems that casio cg50 has some new factures but do you think casio cg20 3D graphing program is better than the cg50?
I want to buy one calculador ,I am at the university and I study physics.I was thinking to buying the casio cg20 for the reasen that I explained before but what other calculetors could you recommend me for this degree(I'm going crazy searching for calculators)?
I do think Graph3DP is still much better than Casio's 3D grapher on the fx-CG50 (I also wrote it, so I'm biased, but luckily it runs just fine on the fx-CG50! When you need it, it's here: www.cemetech.net/programs/index.php?mode=file&id=727
For general selection of calculators, take a look at this video I published in 2016 that remains relevant: ruclips.net/video/1xoHjpOOVV8/видео.html

Can this calculator do polar coordinate functions?
When is Doors 9.0 Coming out schools started already and I can't wait, I've told a lot of my friends about this exciting program already! I can wait!
Congratulations! Screen size?
My calculator is giving me answers in terms of pi. How do I change that back and forth?
I reset my calculator and the conversion program is gone how can i get it back?
Connect it to your PC and go to the casio website to download the addon
Is it possible that you can make an emulator for this calculator for your web-based simulator site? A smartphone app and Linux-compatible software would be nice too. Thanks for making the previous online ti-84+ SE emulator.
You're welcome (Lars is talking about www.cemetech.net/projects/jstified/ , if you're not familiar). Making it work for the Prizm is something I'd like, but the architecture of the Prizm is completely different from TI's calculators, and since jsTIfied basically emulates your calculator's hardware in Javascript, this would require essentially starting from scratch. It's unliekly I'll get around to it in the near future.
im geting the casio fx-cg50 tomorrow why does it do 3d graphs and soreadsheets when all I whant is for my maths because that where im doing it on khan academy maybe chemistry to and hopefully progress to highter, advanced and pure maths.
Well, because of that latter part. When you get to advanced and pure maths, or engineering, or physics, you'll need some of those more advanced features!
AAAs are great.
I'm shocked how frequently this video gets this response. Clearly I need to make a video investigating preferences about rechargeable vs. AAA batteries.
Can someone please explain why those calculators are so expensive compared to phones?
Money I guess. The fx-CG50 only had 16 MB and the screen is not very good
@@OvPdTurtle I have one and the screen IS really good
Cool vid
How long is its battery life?
But can it do fourier?
HP Prime vs CG-50 ?
Can you do integers in this calculator?
It's probably a little late now, but can you be more specific? You can certainly work with integers, and you can use the round() command to turn floats into ints.
hi, they added MicroPython 1.9.4 on it in latest FW 3.20 ... seems to be cool ;-)
Casio did? That's pretty amazing; I'll go take a look.
I don't suppose you could make a video about it :)
I'm planning to make a video about it in the next few days!
Hi, How can you upload an image to put a graph on?
1) Go to sc.cemetech.net
2) Upload an image that is g3p folder.
KermMartian great thankyou!
I’m not sure if I can use a graphic calculator during exam..
My teacher would take it away
Certain ones are allowed. You can look it up online. The fx-CG50 is allowed on most exams if you use the examination mode it comes with.
How would we know? That would depend on your teacher or school.
I'd rather have replaceable batteries. And it's got Python!
Hi there. Can this calculator perform symbolic math?
Not with the built-in tools. EigenMath by gbl08ma (www.cemetech.net/programs/index.php?mode=file&id=1144) does allow for symbolic math, however.
How I can load games ad other stuff on the fx cg50?
I search a lot, but I didn´t find any tutorials how to do this.
Can anyone help me? (My englisch is bad, I know... But I came from Germany...)
Good question, and something I should make a video about at some point. Here's a good explanation for now: www.cemetech.net/forum/viewtopic.php?t=7549

Hmm, I'm not sure off the top of my head. Can you please post a topic on the Cemetech forum ( www.cemetech.net/forum ) about what game(s) you tried, and what happened when you tried, and we'll try to help you debug?
KermMartian Thanks! I do it so fast I can.
This Casio or Hp Prime? 🤔🤔🤔
HP Prime
Depends what for. If you need to use it in high school or on the SATs, you probably won't be allowed to use the Prime. If you're a professional, in college, or studying engineering, the Prime hands-down.
KermMartian 👍👍👍
Antonio Barba, você é brasileiro? Valeu. 👍👍👍
The best is HP 50g!
AAA Batteries are boon in disguise. The rechargeable batteries are costlly, and few years down when the model gets obsolete , chances are , batteries may get obsolete too.
Is there programming?
Yep, they do still have their BASIC programming capabilities, and it is very fast running on the new calculator.
tifreak8x Thank you! Thinking of buying this to replace my TI-84 plus.
There's good and bad with that, though. The casio programming community is small and has very little support in terms of programs being written for it. The 84+CE has an explodingly active community with new games and programs being made daily, and a C programming environment that continues to expand as such. You should poke around on Cemetech and ask questions before solidifying yourself in your purchasing decision :)
As +tifreak8x says, while the Prizm's processor is faster and the platform is more open, the TI-84 Plus CE has a much broader community and more programming tools.

Rechargeable batteries usually die within few years forcing many user to dispose the calculator, that is planned obsolesce. Moreover, Lithium batteries they are safety hazard under high pressure and temperature. They are not replaceable. Except weight and size factor, they have nothing great about them.
