public class FEllipsePublic Class FEllipseNo code example is currently available or this language may not be supported.The general form of an ellipse is:
((x - h)2 / a2) + ((y - k)2 / b2) = 1
... where h and k are the center coordinate, a is the x radius, and b is the y radius.
If center X, Y is -5, 2, the X radius is 3, and the Y radius is 4, the same equation can be written as:
((x + 5)2 / 9 + ((y - 2)2 / 16
The focal points are found using c2 = b2 - a2
... meaning c = Sqrt(Pow(RadiusY, 2) - Pow(RadiusX, 2)).
The focal points are placed on the major of the two axes, if one is found, otherwise, on the X axis.
