Integration by Substitution (also called u-Substitution or The Reverse Chain Rule) is a method to find an integral, but only when it can be set up in a special way.

Integration by substitution consists of finding a substitution to simplify the integral. For example, we can look for a function u in terms of x to obtain a function of u that is easier to integrate. After performing …

Nov 16, 2022 · Let’s work some examples so we can get a better idea on how the substitution rule works. Example 1 Evaluate each of the following integrals. In this case it looks like we have a cosine …

Nov 11, 2025 · At first, identifying an appropriate substitution to facilitate the evaluation of the integral may not be straightforward. However, we will proceed systematically to transform the given integral …

When dealing with definite integrals, the limits of integration can also change. In this unit we will meet several examples of integrals where it is appropriate to make a substitution.

Dec 2, 2025 · Integration by Substitution is achieved by following the steps discussed below, Step 1: Choose the part of the function (say g (x)) as t which is to be substituted.

The integral of a function is simplified by this method of integration by substitution, by reducing the given function into a simplified function. Let us learn the process of integration by substitutions, check …
