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 $I = \int {x\cos 2xdx}$ H

4. ]π/4. 0. =. ### To do this integral, regognize that sin 3 x = sin(x)·sin 2 (x), and write the new integral: . Now use the identity . to replace sin 2 x and write the new integral. Now this new integral is a sum of two integrals, the last of which can be evaluated easily using the substitution u = cos(x), like this:. The first integral is easy, it's just -cos(x).The second is easy because of the substitution. integral(Cos(Sen(2x))(Cos(2x))dx. Examples; Random.

The integral of cos (2 x) is (1/2)sin (2 x) + C, where C is a constant. First, we write \cos^2 (x) = \cos (x)\cos (x) and apply in­te­gra­tion by parts: If we apply in­te­gra­tion by parts to the right­most ex­pres­sion again, we will get ∫\cos^2 (x)dx = ∫\cos^2 (x)dx, which is not very use­ful. The trick is to rewrite the \sin^2 (x) in the sec­ond step as 1-\cos^2 (x).
