In the Equation Solver app, you cannot store the roots. But, if you use the solve command in Run-Matrix, you can store the answer by hitting the arrow button (under tan), and assigning the answer to a alpha (So Alpha-A). Then you can use the A in future calculations. You can also 'save' the roots if you use the graph menu - i.e. graph the function, G-Solve to find roots, intersections, etc., and if you press EXE when on one of the roots/intersections/etc., on the CG50, the point will set and stay there to be seen.
Standard form is a button. If you look at the keypad, you should see a button that looks like a fraction. In run matrix (or whenever you are entering a number in graph, table, etc.), you can either hit that button first, and the blank template appears on screen, and you use the arrow/navigation button to move to the position and enter your number. You can also hit the number first (say 2), then the button, and it will place that 2 in the numerator position, then you enter the denominator. To enter a mixed fraction, you hit SHIFT and the standard form button.
Yes. You can do very large matrix problems - enter your own dimensions. Go into the Run-Matrix menu, click F3 (Mat/VCT), choose a Matrix (they are A - z) . Enter the dimensions you want. It will create the matrix and you can enter the values. You then you use the Matrix names in your calculations - provided the dimensions correspond correctly, you will be able to do the equations.
Hiya please could you do a video of using the CG50 to draw basic graphs. I bought one for A Level maths but can't even work out how to draw basic graphs and sin/cos/tan graphs.
The answer to your matrix question is yes, you can do matrix operations with complex numbers. You have to go into the Run-Matrix Menu and choose SetUp (Shift/Menu) to make sure Complex numbers is selected, but then you should be able to solve with complex numbers in matrices. As you your Electrical engineering question, I don't know what type of math that involves, but the CG50 pretty much does all math required for calculus and advanced math courses, so I can't imagine it wouldn't have everything you need for engineering. Here's a quick reference for the features: www.casioeducation.com/resource/techspec/module-fx-cg50%20prizm.pdf if that helps.
Absolutely. In the main menu, go to Graph and you can graph the equations. The default is y= where you enter the coefficients and x-variables, but there are options to do x= equations or parametric, polar, etc. Pretty much whatever you need.
Ok, so this is what I am doing; 1. Creating a word problem I am: Forecasting trends of possible units to be purchased based on measurable possibilities which are variables. Variables are the formulas that represent: 1a: time (C) percentage representing possible attempts to be made last year and the time allowed to do so (total man hours available). 1b. Previous years total opportunity the time needed to increase (productivity to increase purchases) 1c. Prior year trend margin of profit and profit needed 1d. Amount of current attempts needed based the amount of attempts taken previous year. 2. Use calculus to put this problem into an expressed using variables. 3. then used algebra/ more than likely I’ll use the quadratic formula to express this into polynomial-form . [this is for work] not a classroom assignment 4. Input the polynomial in this graphing calculator to illustrate by graph, so my question was; 👇🏿 ✅“will this calculator be able to display this type of algebraic equation ”? and, (I do) or (I do not )need to purchase the Casio classpad II FX-CP400 . Thank you for your help I only went as far as business calculus in school I was an English Major. However, I respect the discipline. ✅Thank you again for your help✅
@@sidewinder4718 Honestly, this sounds like a linear programming problem to me, which could be done on the calculator easily (no calculus needed and quadratic equations unnecessary since this is not a parabolic situation). Basically, each of your equations is graphed as an inequality (i.e. the constraints) which creates a 'feasible region" (the intersection of all the possible solutions to each constraint. The profit maximization calculation basically plugs in the coordinates from all the intersection points to find your solution. I would actually recommend doing this on the free software ClassPad.net, especially if you don't already have a calculator, especially if you are thinking of doing a presentation, since you can write your explanations right on it. If you already have the calculator (CG50) that will do this as well - you just enter each equation separately and as an inequality. Here is an example of a linear programming model. It doesn't obviously match your equations, but it gives you an idea of what you have to do. Basically, your 1a-d becomes constraints - use the same variables (x and y to represent time and opportunity I think....). Then a profit equation that incorporates those variables. You graph the constraint equations to create the feasible region. Look at the intersection point coordinates and plug those in to your profit equation to determine the profit. You might need several different graphs if you have more than three variables - you want to graph in the two variables and use them to determine the Profit or time calculation needed. Here's the link to an example: classpad.net/classpad/papers/share/9b821b33-0f33-4110-8d20-19d8986971ce You can work in this example. If you want to save it, you need to create an account in ClassPad.net. But this might help you think about your problem. You can email me at karengreenhaus@gmail.com if you want to just talk directly - happy to help!

If you look at some of the videos for CG10 and the other graphing calculators from Casio on my channel, the CG50 follows the same exact process. Another great resource is the Quick Start guide which will show you the basics - www.casioeducation.com/resource/manuals/prizm-fx-cg50/Quick%20Reference%20Guide.pdf Additional, there are tutorials on the Casio site - any of the CG10/Prizm videos will be the same as the CG50 calculator. I will also make some basic graph video specific to CG50 in the coming weeks!
How do you save the results of the equations onto the memory? For example saving the roots onto memory A and memory B.
In the Equation Solver app, you cannot store the roots. But, if you use the solve command in Run-Matrix, you can store the answer by hitting the arrow button (under tan), and assigning the answer to a alpha (So Alpha-A). Then you can use the A in future calculations.

Hi Karen, can this calculator solve quadratic inequalities?
Yes it can! I’ll make a video on it....but basically it’s in the graph menu. You can Change the equal to an inequskity and enter any function.
@@karengreenhaus6713 Thank you. I will explore that.
can someone teach me how to input standard form on this graphing calculator
Standard form is a button. If you look at the keypad, you should see a button that looks like a fraction.

Does this calculator works for bigger equations like 9*9 matrix
Yes. You can do very large matrix problems - enter your own dimensions. Go into the Run-Matrix menu, click F3 (Mat/VCT), choose a Matrix (they are A - z) . Enter the dimensions you want. It will create the matrix and you can enter the values. You then you use the Matrix names in your calculations - provided the dimensions correspond correctly, you will be able to do the equations.
It should. Ill double check.

Just go to the graph menu, type in your equation and enter "draw". A graph for your equation(s) should show up if it is appropriate.
Can you solve a matrix with complex numbers with it?
and would you recommend it for an Electrical engineering student?
The answer to your matrix question is yes, you can do matrix operations with complex numbers. You have to go into the Run-Matrix Menu and choose SetUp (Shift/Menu) to make sure Complex numbers is selected, but then you should be able to solve with complex numbers in matrices.
