20 Most Recent Casio FX-9750GII Graphing Calculator Questions & Answers

Your function is not correctly defined. If graph is function y=f(x), variable must be x; if graph is polar, variable must be theta, and if graph is parametric, variable must be t. This does not cover all possible cases. Check the graph type and the definition of the function.

Choose one of the inequality type graphs by pressing F3 Type. Press F6 for the arrow on the right, you will get the other types For example press F1 to select the Y greater than type graph. Notice that on the top line Graph Func: Y>. From now on all the graphs you will draw will be Y> some function in X. Start entering the function. As you start the screen will show Y1> Enter the function for example sin(X^2). Use the X, theta, T to input the X variable. Press the EXE key to complete the function line. The screen will look like on the following screen grab Press the F6 key Draw to get your graph and the shaded region, as on the following picture:

In Casio Graphing calculators, MA error stands for Math Error. The calculation overflows the memory.

In parametric graphing mode, pressing the X, theta, T button will enter the Theta variable.

Just wondering if the other functions are working. The manual references setting up angle unit and setting up the "comp for mode" in the setup. The keys you should be pressing to do this calculation are on page 51 (2-31) of the attached manual. http://support.casio.com/manualfile.php?rgn=5&cid=004002013 Good luck. If unsuccessful, please repost. Paul

Check the calculator with a simple 2X2 matrix that you can invert by hand easily and see if it gives you the wrong inverse for it. It is also possible that YOU made the mistake.

In Run/Mat screen, press the OPTN key followed by F6, the F3:Prob. The nPr and nCr tab are accessible. Type n then the relevant tab, followed by the r-number.

go google and type in-- operating instructions for ( make and model of ) calculator there is a page somewhere that will have a pdf version that you can down load

You are confusing different technologies. In The TI8x family of calculators, you need to turn Diagnostics On to get R and R^2. On the Casios, if a correlation coefficient is defined it will be displayed by default with other statistics.

On this calculator you have to use the "^" key. For example, 2 to the exponent 3, type 2, hit the "^" key and type 3. Your answer should be 8, as 2^3 = 8 or the long way, 2 x 2 x 2 = 8. Good luck. Paul

The Window parameters control the width and length of the graphing screen. The distance equation is a formula to use to calculate the distance between two points known by their coordinates. The window dimensions have nothing to do with calculations. Or maybe I don't understand the question.

In Run/mat press SHIFT MODE (Setup). Scroll till you reach display. Select any thing except scientific. In general, choose Norm1 or Norm2

There is a program on page 253 of the manual (http://support.casio.com/manualfile.php?rgn=5&cid=004002013) to get the prime factors of any number. You could modify the program to get all the factors. Another way would be to do it manually. I start with the number 1 and go up to the square root of the number. The square root of 120 is 10.95, so let's go up to 11. Using 120 as an example: 120 /1 = 120 thus factor is (1, 120) 120/2 = 60 thus factor is (2, 60) 120/3 = 40 thus factor is (3, 40) 120/4 = 30 thus factor is (4, 30) 120/5 = 24 thus factor is (5, 24) 120/6 = 20 thus factor is (6, 20) 120/7 = 1.7 thus 7 not a factor 120/8 = 15 thus factor is (8,15) 120/9 = 13.3 thus 9 is not a factor 120/10 = 12 thus factor is (10,12) 120/11 = 10.9 thus 11 is not a factor. Good luck. Paul

On my Casio's on the bottom row (centre) is a button called EXP. That is the one you are looking for.

They're both giving you the same number. 1.953125E-03 means 1.953125 * 10^-3, which is 0.001953125 .

Make sure your calculator is set to the desired angular mode. The quotient of 120 divided by the tangent of 68 radians is about -58.82, as your calculator is giving you. The quotient of 120 divided by the tangent of 68 degrees is about 48.48 . The quotient of 120 divided by the tangent of 68 grads is about 65.97 .

Sorry, it does not display results as radicals, let alone simplify them.
