WebSal was simply expanding the expression (1/2 (1-cos2x))^2. 1/2 squared is 1/4 and (1-cos2x) squared is (1-cos2x) times (1-cos2x). If you recall from Algebra that (a-b) (a-b) = a^2 -2ab + b^2, then let a = 1 and let b = cos2x and multiply it out. a^2 = (1) (1) = 1, -2ab = -2 (1) (cos2x) = -2cos2x. b^2 = (cos2x) (cos2x) = cos^2 2x.
