The trick is to rewrite the \sin^2 (x)sin2(x) in the sec­ond step as 1-\cos^2 (x)1 − cos2(x). It is used to transform the Answer link.The most straightforward method of solving it is to use the Taylor expansion of cosine replacing x with x2: cos(x2) = ∑n=0∞ (−1)n(x2)2n (2n)! and then integrating term by term within a certain domain of accuracy. ∫cos2(x)dx = cos(x)sin(x) + ∫(1 − cos2(x))dx = cos(x)sin(x) + x − ∫cos2(x)dx.
