    Finding two points X, Y . Info given, Angle and radius

    I have the angle 2pi/3 and the radius of 6. What is the formula I'd use to calculate the exact coordinates?

    I think I figured it out, multiple the X,Y coordinates to by the radius. X = -1/2(6) Y = sqrt3/2(6) which gives me the coordinates (-3, 3sqrt3)

    Your point is \left( {r\cos (\theta ),r\sin (\theta )} \right).
