Is 3pi 2 on the unit circle?
cos(α) is an abscissa (X-coordinate) of a point on a unit circle, which radius makes an angle α with a positive direction of the X-axis, counting from that positive direction of X-axis counter-clockwise. Angle 3π2 corresponds to a point with coordinates (0,−1) on a unit circle. Therefore, cos(3π2)=0 .
