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.

Free Online U-Substitution Integration Calculator - integrate functions using the u-substitution method step by step

Jul 23, 2025 · Integration by U-Substitution is a technique used to simplify integrals by substituting a part of the integrand with a new variable, uuu, to make the integral easier to solve.

Dec 21, 2020 · In this section we examine a technique, called integration by substitution, to help us find antiderivatives. Specifically, this method helps us find antiderivatives when the …

Key takeaway: Sometimes we need to multiply or divide the entire integral by a constant, so we can achieve the appropriate form for u -substitution without changing the value of the integral.

May 11, 2025 · Learn u-substitution in calculus with clear examples. Master how to choose 𝑢, solving integrals, and changing limits for definite integrals step by step.

In calculus, integration by substitution, also known as u-substitution, reverse chain rule or change of variables, [1] is a method for evaluating integrals and antiderivatives.

U-Substitution Integration, or U-Sub Integration, is the opposite of the The Chain Rule from Differential Calculus, but it’s a little trickier since you have to set it up like a puzzle. Once you …

\ (u\)-substitution is a great way to simplify integrals. It is a technique used in many other forms of integration such as integration by parts and the infamous trig sub.

In the u-substitution formula, the given function is replaced by 'u' and then u is integrated according to the fundamental integration formula. After integration, we resubstitute the actual …
