What is integration in calculus?

In calculus, integration by parts is a theorem that relates the integral of a product of functions to the integral of their derivative and anti-derivative. It is frequently used to find the anti-derivative of a product of functions into an ideally simpler anti-derivative.

What is integration of trigonometric functions?

Some integrals involving trigonometric functions can be evaluated by using the trigonometric identities. These allow the integrand to be written in an alternative form which may be more amenable to integration. use trigonometric identities to integrate sin2 x, cos2 x, and functions of the form sin 3x cos 4x.

How to integrate trigonometric identities using different techniques?

These techniques use different trigonometric identities which can be written in an alternative form that are more amenable to integration. The integration of a function f (x) is given by F (x) and it is represented by: R.H.S. of the equation means integral f (x) with respect to x.

How do you find the integral of a trigonometric function?
