Integrals
U-Substitution
The integration counterpart to the chain rule.
U-substitution is a method for finding integrals. Using the Fundamental Theorem of Calculus, it corresponds to the chain rule for differentiation. It involves replacing a complex part of the integrand with a single variable 'u'.
