Consider the integral $\int_{-2}^{2} e^{5-3 x} d x$.
(a) Solve this integral by using $u$ -substitution while keeping the limits of integration in terms of $x$.
(b) Solve the integral again with $u$ -substitution, this time changing the limits of integration to be in terms of $u$.

Key Concepts

u-Substitution Method

u-Substitution is an integration technique used to simplify integrals by making a substitution for a function within the integrand. This method effectively reverses the chain rule from differentiation, allowing one to rewrite the integrand and differential in terms of a new variable, which can simplify the integration process.

Definite Integrals

Definite integrals compute the exact area under a curve between two specific limits. They yield a numerical value and require the evaluation of the antiderivative at the boundaries of the integration interval.

Changing Limits of Integration

When applying a substitution in a definite integral, one may choose to keep the original variable limits and substitute back after integrating, or convert the limits to match the new variable. Changing the limits of integration involves updating the endpoints according to the substitution, ensuring that the integral remains correctly defined over the new variable's domain.
