U-substitution is a technique in calculus for evaluating definite and indefinite integrals by making a substitution in the integrand. The substitution involves replacing the independent variable in the integrand with a new variable, often denoted by "u", that is related to the original variable through a differentiable function. This allows us to simplify the integrand and make it easier to integrate. The key idea behind u-substitution is to make use of the chain rule of differentiation.
