how to prove that the area of a trapezoid is given by the following function : A= (2-sinθ)/(2cosθ)

point T is located on the unit circle whose equation: x ^2 + y ^2 =1 , at the angle θ from the positive x axis where 0 ≤ θ<π /2 as in the adjacent figure: 1)prove that the area of a trapezoid OBQP is given by the following function : A= (2-sinθ)/(2cosθ) 2...
