The key is the shifted key of the right parenthesis.
[SHIFT ][ )] (x^-1) will calculate the reciprocal of a number.

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.

I do not know what a range is and where to find it on a Casio FX 9750GII Calculator


In statistics, the range of 1-var a data set is the difference between the largest value and the smallest. R=Xmax-Xmin
In functions: the range of a function is the interval (or the Union of intervals) of the real line where the dependent variable takes it values.
Ex: sin(x). Whatever the value of the independent variable x, the values of the function sin(x) are in the closed interval [-1,1]. The range of the functions sin(x), and cos(x) is [-1,1].
No use of a calculator for finding the range of functions.

Fx- 9750gii ... I deleted the table on my table


If the table contains experimental (statistical) data that you gathered and put in a table on the calculator, then I am sorry to say that if table is deleted there is no way to get the data back. You will have to renter it.
However if it is a table connected to a function you graphed then the table can be regenerated: Type in the function anew, press the table function key, then graph it.

How do I graph sinx on my Casio fx-9750GII calculator?


Turn calculator ON
If you see no icons, press Menu
Press 3 (Graph) draw your function. (more on that later).
If the first line of the display show Graph Func : Y= you should be able to draw your function.
If it says anything else, press F3 TYPE to select the graph type and select functional by pressing F1 key Y=.
After the graph type is set to Y=, type the second member of your function y= f(x) on the first line. Make sure the = sign after Y1= remains highlighted after you move cursor. Otherwise select the function by pressing F1:SEL. Press F6 Draw.
Be careful with trigonometric functions. If angle unit is radian, set window Zoom to standard. If angle unit is degree, you must open the Window utility and set Xmin=-190, Xmax = 190 to see at least a period.

Where is the math button on the casio fx-9750G11


It is a calculator and prqactically every button is a MATH button. It depends on what MATH you intend to do. Put the calculator in Run/Mat screen then press the OPTN key. You will see several tabs. Press the function key under a TAB and explore what is offered. Go through all the keys (F6 also) and see what the new tabs do.
In general it is most helpful to read the manual that shipped with the calculator.

I need an inverse log button on the casio calculator 9750GII.... does it have one??? I know how to do log, but can't find the inverse.


The log base 10 function has an inverse: It is the 10 ^x function. It shares the same physical key with the decimal log. Use [SHIFT][LOG].
The natural log (LN) has an inverse alos and that it the exponentila function e^x. It shares the same physical key with it.
