"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.

The formula is used to transform one integral into another integral that is easier to compute. Thus, the formula can be read from left to right or from right to left in order to simplify a given integral.

Jul 23, 2025 · Integration by substitution or u-substitution is a highly used method of finding the integration of a complex function by reducing it to a simpler function and then finding its …

There is no defined formula for integration by substitution. Based on the given function, the part of the function which is to be substituted is substituted with a new variable.

May 24, 2025 · When applying the substitution rule to evaluate definite integrals, it is crucial to adjust the limits of integration accordingly. The new limits must correspond to the substituted …

Learn integration by substitution with the formula, step-by-step guide, and examples. Practice solving integration by substitution questions effectively.

One of the most powerful techniques is integration by substitution. With this technique, you choose part of the integrand to be u and then rewrite the entire integral in terms of u.

Dec 29, 2024 · This section introduces integration by substitution, a method used to simplify integrals by making a substitution that transforms the integral into a more manageable form.

Integration by Substitution for indefinite integrals and definite integral with examples and solutions.

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.
