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.
Circles and Ellipses

General Form:
Standard Form:

h =
k =
a =
b =
The center of the ellipse is at (h,k). The width of the blue box is determined by a and
the height is determined by b. The edges of the blue box, which is what constrains the
ellipse, are at (h a, k b). Try different values of h, k, a and b to see their effect.
When a = b, you have a circle.  The General Form was derived by multiplying the Standard Form by ab. It may not be fully reduced.
