    everything seems in order except the period

    you said it was 2pi/5 or 360/85....it should be 360/5 degrees, which is 72 degrees. But that seems like you made an honest mistake and meant to type 360/5.

    also, 85 degrees is 17pi/36 radians, why did you put the minus sign in front?

    otherwise, good job!
