scrnGC2: Calc Input
scrnGC3: f(x) Plot Input
scrnGC4: g(x) Plot Input
The inputs above will be hidden when the program finally gets launched. Currently, I am not hiding them even when you close the calculator. The purpose of the inputs is to help in debugging. This allows you to enter simple code on the calculator screen but the program translates the input to javascript math. Give it a try and see if you notice any obvious problems or have suggestions for improvements.

Solve the variation problems below.
Note: Each problem has two (2) answers.
Decimal answers should be rounded to the nearest hundredth.

If   y = kx,  x and y vary directly.

If y = k/x,  x and y vary inversely.

If z = kxy,  z varies jointly with x and y.

If z = kx / y2,  z varies jointly with x and inversely as the square of y.
