The calculator can't identify that this is a surd unless you input it as a surd, ie as 3/(4*sqrt(5))= when it will then show the equivalent form 3*sqrt(5)/20 (obtained by multiplying top and bottom by sqrt(5)) and you can swap between the two forms using the S<>D button. Even adding the next 4 decimal places (hidden) won't allow the calculator to identify the underlying surd as this is simply too complcated a calculation.

The variable theta is reserved for polar plots. So if you want to graph functions of the form y= expression, you must use the default variable x. Thus draw y=sin(X). Make sure your calculator is configured with the correct angle unit (degree or radian).
If you use degrees the window dimensions for x must cover an interval of 360 degrees, to have a full period. If angle unit is radian, then choose an x-interval between [-pi and pi] or between [0 and 2pi]

The capability of these calculators to handle irrational numbers in radical form is limited to square roots. Roots of index other than 2 are always displayed in their decimal representation.
If the calculator IO mode is set to MathIO, square roots will be displayed with the radical symbol. More complicated expressions with square roots might not be preserved and will be given as decimal numbers.

### How come when i try to do inverse trig function on my fx-9750 gii calculator it says Ma error?

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.

### How to write a program on fx-9750 calculator

If you want to learn how to program this calculator, I suggest you visit the Casio World website to download a copy of the manual for the FX-9750GPlus (the older version of the calculator). The last chapters contain sample programs you can type in your calculator. Study the programs specially the Input/Output and a few commands and experiment with them. With practice you will graduate to more involved programming.

On the site you will also find a link to the program library for the FX-9750GPlus. Download them and transfer them on the calculator.

### How do I factor using the fx-115 ES calculator? would a problem like 9x^2+24x+16-Z^2 be solvable on this calculator? If not, does Casio sell any calculators that would help me factor this equation?

No, your calculator cannot factor polynomials. You need a calculator that has a CAS (computer Algebra System)
Yes Casio sells calculators with CAS: The FX-Algebra 2.0 and 1.0, the FX-9860GPLUS/GII SD, the GRAPH85 or 80 and the Graph 100+. You also have the CLASSPAD Series 300PLUS and 330.
TI and HP also have CAS calculators.

Texas Instruments
TI 89 /Titanium, Voyage 200PLT, TI92PLUS (discontinued), TI Inspire CAS.

Hewlet-Packard
HP 48G/G+/GX, HP40G, HP49G/G+ and the top of the line HP50G
