WebApr 13, 2024 · Now, we can substitute u = cos x and du = -sin x dx to transform the integral into a simpler form: ∫ (cos^2x - 2cos^4x + cos^6x) dx = ∫ (u^2 - 2u^4 + u^6) (-1/ sin x) du = - ∫ (u^2 - 2u^4 + u^6)/sin x du. This integral can be evaluated by using the power rule of integration. By substituting back u = cos x, we get the final solution: WebEvaluate the Integral integral from 0 to pi/3 of cos(2x) with respect to x. Let . Then , so . Rewrite using and . Tap for more steps...

WebJul 26, 2016 · Explanation: Use integration by parts, which takes the form: ∫udv = uv − ∫vdu. For ∫udv = ∫x2sin(x)dx, we let: u = x2 ⇒ du dx = 2x ⇒ du = 2xdx. dv = sin(x)dx ⇒ ∫dv = ∫sin(x)dx ⇒ v = − cos(x) Thus, substituting these into the integration by parts formula, we see that: ∫x2sin(x)dx = −x2cos(x) − ∫( − 2xcos(x))dx ...
