WebExplanation for the correct option. Given that, sin α = - 3 5 and π < α < 3 π 2. ⇒ π 2 < α 2 < 3 π 4. So, cos α 2 is negative as it lies in II quadrant. sin α = - 3 5 ⇒ cos α = - 4 5. Also, cos 2 A = 2 cos 2 A - 1. cos α = 2 cos 2 α 2 - 1 - 4 5 = 2 cos 2 α 2 - 1 2 cos 2 α 2 = 1 - 4 5 2 cos 2 α 2 = 1 5 cos 2 α 2 = 1 10 cos α ...
