Nettet26. feb. 2014 · $\begingroup$ The "Pythagorean Identity" is the key to these. When both powers are odd in a "trigonometric powers" integral involving sine and cosine, you can take your pick of using sine or cosine as the basis for the substitution. When only one of those functions has the "odd exponent", use that one for the substitution. When both … Nettet2. sep. 2016 · If either sine or cosine is to an odd power, a simple substitution reduces it to an algebraic integral: 1) $\int \sin^n (x)\cos^ {2k+1} (x)\, dx= \int \sin^n (x) \cos^ {2k} (x) (\cos (x)\,dx)$ Let $u= \sin (x)$ so that $du= \cos (x)\,dx$, $\cos^2 (x)= 1- \sin^2 (x)= 1- u^2$ and $\cos^ {2k} (x)= (1- u^2)^k$. how do you spell linette
