Why Is Sin Theta Zero? [Solved]

If we started from A and moves in anticlockwise direction then at the points A, B, A’, B’ and A, the arc length travelled are 0, π2, π, 3π2, and 2π. ⇒ PM = 0. So when will the sine be equal to zero? Clearly, if PM = 0 then the final arm OP of the angle θ coincides with OX or, OX'.
