You are one of the few content providers who actually show how to program, save, and recall a function on the calculator instead of using software on a laptop screen. I can't criticize those who use a laptop, but It is far more helpful to see the actions performed on something that will be allowed into a classroom during a test. Even being 11 years old this video was totally applicable to my Nspire CAS CX ii. Great job and thank you.
While a few people below and saying there are built-in functions to solve a quadratic equation already I found this video to be helpful because now I know how to write a program for other formulas that are not pre-installed in this calculator. Thanks
Here is the input for the Law of Cosines, just in case you were wondering. I started off the same way you did, setting the new program to a function, and setting an open bracket. In the box, you want to enter (cos^-1((a^2-b^2-c^2)/(-2*b*c))) and save as lawcos. Now, when you input the length of the sides, the answer will be the angle opposite to the first side you entered. I cannot find a video on this and I think it would be beneficial to make one, but I suck at making videos.
Thank you so much for this tutorial! I wrote a math program in Python, and I don't want to jailbreak my calculator, and I've been trying to figure out how to store a bunch of equations like this. Say, can you put multiple functions into a program?
Check to make sure you are in the "Radian Mode" IT is in the top right hand corner where the settings/battery meter is. You should be able to check under the "Document Settings"
You can also save this to your library and can access it via your button with a notebook and then press 6. As opposed to having to open the program file directly. You can use it in your quick calc.
How do you exit out of the program screen so that there is only the calculation page. I don't want to see the edit program pane after I've made the program .
YO BLESS YOUR FUCKIN SOUL IM DOING AN ALGEBRA REFRESHER COURSE AND THE PROGRAM WE'RE USING DIDN'T SHOW US HOW TO DO IT CORRECTLY SINCE I'M DOING IT THE WAY IT TOLD ME TO BUT GETTING THE WRONG ANSWERS thank you you just saved me like a week
Very helpful, THANK you! One question, can anyone tell me how to close the right window with the function so I have the calculator on full Screen again?
Hi Im having a problem. After I program the formula my calculator won't let me get over onto the actual calculations part of the screen? It doesn't let me actually use the formula.
Using the TI-Nspire, you use the touch pad to hover your cursor to the area you want to input things to and depress the center until you feel a small click.
Technically yes, it should,... As far as I can see, there is no way to just have it open whenever you feel like it. I personally Own this Calculator and have found no way to make that work yet. Let us know if you do!
Save it instead to the MyLib folder and you will be able to access it in catalog under whatever you called the document. Or if you save it under MyLib and then refresh libray it will be there when you open a new document.

There is a polynomial solver built in anyway:
Home > Calculate > Menu > 3 > 3 > >1

Thanks a lot, this has proved very useful in my second semester of AP Chemistry.
this was super helpful! could you please do more this week! like ones what would help on the sat! thanks
Thank you very much. This was much needed.
very clear instructions! Never programmed a thing and could do it.Thanks :-)
Thank you for the Help on the Programming, we will add a note to the video!
Thank You For your help in the Program!
Awesome video, thanks!

if anyone gets an error like sto→:=..........., then you have to go to your program and make sure it is -4·a·c NOT -4·ac
TI CAS is an amazing tool, thanks for the professional assistance, "how to create"
quad formula on it future instruction!
God Bless!

Awesome !!! Thanks !!
thank u so much. i tried a lot of tutorial but didn´t get it, but now I understand how it works thanks. gonna try curve discription :-)
Thanks so much!

Gracias, Great video thanks for the help
How do you exit out of the program screen so that there is only the calculation page. I don't want to see the edit program pane after I've made the program .
Friend'm hard of single and mixed derivatives and indefinite integrals. Do you have any video, Very good your channel. Nspire CX.
Hi Krogan, you need to put multiplication sign between "x" and the parentheses
hi….i have my calculus final in 4 days. could you please post a video on how to program the limit function and the derivative function.
Cold I save multiples functions at the same document?
thanks
Thanks bro ❤

You can do crtl tab, then doc, 5, delete application
Thanks mate
thanks dude
I just use csolve(,x) It even takes out the i's also.
Another method is using the solve function...
how do u make it lowercase?
when I press divide key I DO NOT see a box over a box I just get a "/". WTF?
thx man
I have the 3.9 version. I can't find how to do this
thanks a ton guy! i found two box icon under five instead of four
thats probably because you have a ti nspire cx ii
I thinking solve the formula by myself!
Go to (on the startup screen) [5] Settings -> [2] Settings -> General -> Real or Complex -> Rectangular
how do i write a simple formula for calculating voltage... the equation is V=IR;V=voltage;I=Current;R=resistance.
A better way would have just shown how to use the polyRoots function built-in for the non-CAS version.
If you save it under MyLib and then refresh libray it will be
there when you open a new document.

It not letting me get a split screen
why dont u make a download?
I got an error saying "non real calculations" can I get help?
You've probably tried to enter a polynomial that has no real roots.
how do i get it to show imaginary ans with the quadratic formula.
it keeps saying error.
I don't know what's wrong with mine. Can you help me? The numbers in final result are like 1.424429 and -8.424...

You don't need to do this. Just type in "solve( [insert quadratic equation here]=0,(variable you're solving for))"
+Patrick Nelson That is only for the CAS version of the calculator. The calculator he is using is just the CX.
if you replace "solve" with "nSolve" then it will work without the CAS
Patrick Nelson thats only on the cas
if you replace "solve" with "nSolve" then it will work without the CAS
Does this use a programming language like C++ or is this a programming language on it's own?
are u stupid this a calculator
Programmable calculator
it uses Lua. Not my first choice personally but I'm sure TI has their reasons.
Thanks jvanegas.. maybe they use Lua because it's a lightweight programming language.
Wait, but if this is in the public library, shouldn't it be available on every document?

it tells me no real solution??
Eeyup!

Algebra or 3
Polynomial tools or 8
Find Roots of Polynomial or 1
Roots ( change to complex)
Plug in your #'s
Hit ok
This calculator already has quadratic equation solving capabilities built in!
how?
@@adamquinn3722 If you have the CAS vesion, just type in "solve( [insert quadratic equation here]=0,(variable you're solving for))"
You spelt quadratic wrong...
why i got that there are too many argument??
You have to say quad(a,b,c) and when you type in your function use 3 arguments no more.
