What is Integration in Calculus?
Integration can be defined as the summation of values when the number of terms tends to infinity. It is used to unite a part of the whole. Integration is just the reverse of differentiation and has various applications in all spheres such as physics, chemistry, space, engineering, etc.
Integration of a function or a curve can be used to find useful information such as the area under the curve or volume of the curve, etc. Integration may be of 2 types which are Definite and Indefinite Integration depending upon whether the limits of integration are mentioned or not. There are various methods to integrate a given function which are discussed below.
Methods of Integration
Methods of Integration in Calculus refer to the various techniques that are used to integrate function easily. Many times it is not possible to directly integrate a function, so we need to use a specific technique to reduce the integral and then perform integration. Any method of integration involves identifying the type of integral and then deciding which method to use.
In this article, we will study what is Integration in calculus, methods of integration mainly the method of substitution, Integration by parts, and Integration using Trigonometric Identities.
