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.

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.

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.

Factorial Calculator "A factorial is a function that multiplies a number by every number below it. For example 5!= 5*4*3*2*1=120. The function is used, among other things, to find the number of way "N" objects can be arranged."

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.

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 Casio FX-9750GII... | Answered on Jul 29, 2015

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.
