Key Concepts

Improper Integral

An improper integral typically occurs when the integration limits extend to infinity or when the integrand becomes unbounded or has a discontinuity within the interval of integration. The classification often requires a limit process to handle any potential unbounded behavior.

Continuity on a Closed Interval

A key concept in determining whether an integral is proper is the continuity of the integrand on the closed interval of integration. If the integrand is continuous over the entire interval, the integral is generally proper because it avoids any unbounded behavior or discontinuities.

Endpoints and Discontinuities

When analyzing an integral for being improper, special attention is given to the endpoints. An integral might be improper if the integrand is undefined or diverges at one or both endpoints of the interval. If neither endpoint causes the integrand to be undefined or infinite, then the integral is likely proper.
