Calculates X, Y of position on a Circle or ellipse.
Pass the center X, Y of your ellipse, the degree position, and the horizontal and vertical radii (if they are equal, you're specifying a circle, If not, it is an elongated ellipse).

' Inputs: Pass the subroutine the center X, Y of your ellipse, the degree position, and the horizontal and vertical radii (if they are equal, you're specifying a circle, If not, it is an elongated ellipse).
' Returns: Coordinates in the X and Y parameters.

Sub DegreesToXY(CenterX, CenterY, Degree, radiusX, radiusY, X, Y)
Dim Convert
Convert = 3.141593 / 180 ' pi divided by 180
X = CenterX - (Sin(-Degree * Convert) * radiusX)
Y = CenterY - (Sin((90 + (Degree)) * Convert) * radiusY)
End Sub
