Additionally, we will quickly see how these substitutions help simplify our radical expressions, and enable us to solve problems for both indefinite and definite …This section explores integration by substitution. It allows us to "undo the Chain Rule." Substitution allows us to evaluate the above integral without knowing the original function first. The underlying principle is to rewrite a "complicated" integral of the form \(\int f(x)\ dx\) as a not--so--complicated integral \(\int h(u)\ du\).
Integration by Substitution. "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 first and most vital step is to be able to write our integral in this form: This integral is good to go!
