NettetHow would Integrate the following? $$\int \cos^3(x)\cos(2x) \, dx.$$ I did $$\int \cos^3(x)(1-2\sin^2(x)) \, dx = 2\int \cos^3(x)-\cos^3x\sin^2x \, dx$$ But I find ... Nettet18. mai 2024 · ∫ ( cos^2x sinx ) can be written as ∫ ( cos x )^2 * sinx dx Let, u = cos x. So, du = – sinx dx Thus, ∫ ( cos x )^2 * sinx dx = – ∫ u^2 du Therefore, this is equal to – u^3 / 3 + c. Thus, the answer is – cos^3x / 3 + c (where c is an arbitrary constant) Integral of cos^2x sin^3x ∫ cos^2x sin^3x = ∫ sinx ( sin^2x ) ( cos^2x ) DX

Oct 12, 2015 I = 1 … Nettet3 Answers Sorted by: 13 That's a good way to proceed. So our integral is $$\int \cos^3 x (1-2\sin^2 x)\,dx.$$ Rewrite as $$\int \cos x (1-\sin^2 x) (1-2\sin^2 x)\,dx$$ and let $u=\sin x$. We end up with $$\int (1-u^2) (1-2u^2)\,du.$$ Expand and integrate. Share Cite Follow answered Sep 18, 2013 at 18:31 André Nicolas 497k 46 531 961
