Applications of integration

This course is a part of AP®︎ Calculus AB, a 10-course Topic series from Khan Academy.

Definite integrals are all about the accumulation of quantities. Let's see how they are applied in order to solve various kinds of problems.

This course contains 13 segments:

Finding the average value of a function on an interval

Connecting position, velocity, and acceleration functions using integrals

Using accumulation functions and definite integrals in applied contexts
