Integrate cosx

Before going to find the integral of cos x, let us recall what is integrate cosx. An integral is nothing but the anti-derivative.

Integral of Cos x is Sin x. Integral is the process of finding the area under the curve. Integration of Cos x gives the idea of the region covered under the cosine trigonometric function. The integral also called the Antiderivative of a function exists when the function is differentiable. Integration of Cos x is possible as the cosine function is also differentiable in its domain.

In this section we look at how to integrate a variety of products of trigonometric functions. These integrals are called trigonometric integrals. They are an important part of the integration technique called trigonometric substitution , which is featured in Trigonometric Substitution. This technique allows us to convert algebraic expressions that we may not be able to integrate into expressions involving trigonometric functions, which we may be able to integrate using the techniques described in this section. In addition, these types of integrals appear frequently when we study polar, cylindrical, and spherical coordinate systems later. For integrals of this type, the identities. After applying these formulas, simplify and reapply strategies 1 through 3 as appropriate. Use strategy 2. These formulas may be derived from the sum-of-angle formulas for sine and cosine.

Functions involving trigonometric functions are useful as they are good at describing periodic behavior. This section describes several techniques for finding antiderivatives of certain combinations of trigonometric functions. This integral is easy since the power of both sine and cosine is 1.
