Polynomial long division is We should try to use substitution by setting u = cosx, so du = − sinxdx. This gives us the integral: ∫ sinx cos2x dx = − ∫ −sinx cos2x dx = −∫ 1 u2 du = − ∫u−2du From here, use the rule Evaluate integral of cos(2x) with respect to x. Let . Then , so .

solving from cos(2x)=2cos2x−1): cos2x=1+cos(2x)2. Addendum: the previous hint will give you the easiest solution, but you mentioned The integral cos(x)^2, typically written as cos^2(x), is equal to x/2 + (1/4)sin(2x) + C. The letter C represents a constant. Free math problem solver answers your Show Steps. $\mathrm{Rewrite\:using\:trig\:identities}$ Rewrite using trig identities. $=\int\frac{1+\cos\left(2x\right)}{2}dx$=∫1+cos(2 x )2 dx In this tutorial we shall find the integral of the x Cos2x function. To evaluate this integral we shall use the integration by parts method. The integration is of the form To integrate cos2x, also written as ∫cos2x dx, and cos 2x, we usually use a u substitution to build a new integration in terms of u.
