sin pi/2 = sin 90 = 1 then need to divide through

I expressed the cotangent as 1/tan = cos/sin using the sum of angles expand cos(a + b) and sin (a + b) sin pi/2 = sin 90 = 1 and cos pi/2 = cos 90 = 0 substitute and simplify given theta - pi/2 so theta is in the 2nd quadrant tan is negative in the second quadrant
