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

NettetFrom ∫cosx* (1-sin^2 x) dx you will get: ∫ (1-u^2)du = ∫du - ∫u^2 du = u - (1/3)*u^3 Substitute back and i got the same result: sinx- ( (1/3)*sin^3 x) + C • ( 53 votes) Flag Daniel Chaviers 8 years ago It's valid as well, from what I can tell. Nettet13. apr. 2024 · Another method for solving the integral of sin^4x cos^2x is to use integration by parts. Let u = sin^3x and dv = sin x cos^2x dx. Then, we have du/dx = … hach rose schirripa \\u0026 cheverie llp
