# Limits of Integration — AP Calculus Definition & Exam Guide

## Definition

The limits of integration are the values that determine the range over which an integral is evaluated. They specify the starting and ending points on the x-axis for finding the area or calculating other quantities using integration.

- [Definite Integral](/ap-calc/key-terms/definite-integral): A definite integral is used to find the exact value of an area under a curve or to calculate other quantities. It involves integrating a function between specific limits.
- [Indefinite Integral](/ap-calc/key-terms/indefinite-integral): An indefinite integral represents a family of functions that differ by a constant. It does not have specific limits and is often used to find antiderivatives.
- [Riemann Sum](/ap-calc/key-terms/riemann-sum): A Riemann sum is an approximation method for finding areas under curves by dividing them into smaller rectangles. It becomes more accurate as these rectangles become narrower.
