"Web31 jul. 2016 · Explanation: The trick to finding this integral is using an identity--here, specifically, the cosine double-angle identity. Since cos(2x) = cos2(x) −sin2(x), we can rewrite this using the Pythagorean Identity to say that cos(2x) = 2cos2(x) − 1. Solving this for cos2(x) shows us that cos2(x) = cos(2x) + 1 2. Thus: ∫cos2(x)dx = 1 2 ∫cos(2x) + 1dx " - Identities of cos 2x
