Mar 14, 2024 (1 −sin2x)2 Explanation: factor using the a-c method let u = sin2x ⇒ 1 − 2u + u2 the factors of + 1 which sum to - 2 are - 1 and - 1 ⇒ 1 − 2u + u2 = (1 − u)(1 − u) = (1 −u)2 change u back to sin2x
WebLearn about simplify using our free math solver with step-by-step solutions. 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. Hope this helps.
