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.

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).

The easiest way to calculate this integral is to use a simple trick. 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 following is a list of integrals (antiderivative functions) of trigonometric functions.For antiderivatives involving both exponential and trigonometric functions, see List of integrals of exponential functions.

=cosx - 2/3cos^3x + C Use the identity cos(2x) = 1 - 2sin^2x. =int(1 - 2sin^2x)sinxdx Multiply out. =int(sinx - 2sin^3x)dx Separate using int(a + b)dx = intadx + intbdx =int(sinx)dx - int(2sin^3x)dx The antiderivative of sinx is -cosx. Use the property of integrals that int(Cf(x))dx = Cintf(x) where C is a constant. Note that sin^3x can be factored as sin^2x(sinx), which can in turn be written 2018-02-24 Find the Integral (1+cos(2x))/2. Since is constant with respect to , move out of the integral. Split the single integral into multiple integrals.
