Finding the coordinates on the edge of a circle?

Question

Using C#: How do I get the (x, y) coordinates on the edge of a circle for any given degree, if I have the center coordinates and the radius? There is probably SIN, TAN, COSIN and other grade ten math involved... :)

Answer 1

The conversion from polar coordinates (r,θ) to Cartesian: x = r cos θ y = r sin θ

Think of the cos θ = adj/hyp = x/r and sin θ = opp/hyp = y/r
