The integral of cos (2x) is 1/2 x sin (2x) + C, where C is equal to a constant. The integral of the function cos (2x) can be determined by using the integration technique known as substitution. In calculus, substitution is derived from the chain rule for differentiation. For any given value, the cos (ax) = 1/2 x sin (ax) + C.

We recall the double angle trig identity and rearrange it for sin squared x to make [2]. 2012-12-09 Integral of cos(2x) (substitution) - The fastest way to solve it step by step!👋 Follow @integralsforyou for a daily integral 😉📸 https://www.instagram.com/ How to integrate cos^2 x using the addition formula for cos(2x) and a trigonometric identity. 2020-03-26 · The integral of cos(2x) is 1/2 x sin(2x) + C, where C is equal to a constant.

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.
