I believe you must rethink the design of your program
If you have several inputs that lead to a single result you want to keep for further calculations, enter the inputs, calculate your result and store in a variable. The intermediate variables can be set to zero (by precaution) and reused.
Use functions, and subroutines. Usually, in well designed programs, the scope of a variable defined inside a function or subroutine is local :It can't collide with the same name used globally (global scope). If a variable is no longer needed destroy it and reuse it..
SOURCE: how to use trig function keys on my casio fx-300ES
Hello,
You have 3 keys for the main trigonometric functions: [SIN], [COS] and [TAN]
To use them correctly you must set the angle unit to the one your problem calls for.
Press [SIFT][MODE] [3:Deg] for degree, [4:Rad] for radian, [5:Grad] for grad. Dependig on angle unit chosen a small D, R, or G appears on the top of the screen.
If you need the inverse trigonometric functions arcsine, arccosine, arctangent, you access them by first pressing the [SHIFT] key
Thus
arcsine [SHIFT][SIN] (sin^-1)
arcosine [SHIFT][COS] (cos^-1)
arctangent [SHIFT][TAN] (tan^-1)
The syntax for the function is
[SIN] # [ ) ] [=]; [SIN] 30 [ ) ] [=] gives 0.5
[COS] # [ ) ] [=] [COS] 19 [ ) ] [=] gives 0.945518576
Note: if the argument of the functions are numbers, the right parenthesis is not necessary. But if the argument is an expression (with various operations) better put the parenthesis to make sure the calculator is performing as one wants it to.
By the way, there are no keys, or key combinations to calculate cotangent, cosecant, and secant, but you can use the definitions:
cotangent (x) = 1/tan(x) Do not confuse it with tan^-1
cosecant(x) = 1/sin(x) Do not confuse it with sin^-1
secant(x) = 1/cos(x) Do not confuse it with cos^-1
Hope it helps.

I don't know about fx-9750gII, but for fx-991MS
Change the mode to REG
Then
Shift->3(DISTR)->1(P())->give your Z value
SOURCE: i do not know how
Hey it is. Okay, so start with a equation: say, y = -(1 |x|). Now type y = -(1 , then press the [OPTN] button, next to the shift. Next press the [NUM] button or F5. The first menu button should be Abs or absolute value. When your done it should look like this. y = -(1 Abs (x)) then graph it.

From the Run Mode (select it and press exe), enter Setup (Shift Menu) and then highlight Angle. Press the function key that correponds to Deg and then press Exit.
The manual for the Casio Fx-9750GII is here: http://support.casio.com/manualfile.php?rgn=1&cid=004002013 . Other calculator manuals are here: http://support.casio.com/manuallist.php?rgn=1&cid=004 .
I hope this helps.
