This video gives an introduction about the process of integration, which is the inverse process of differentiation. It shows how to obtain the equation of a curve though the equation of its gradient.

This video demonstrates how to use integration to remove dy/dx from equations to obtain an equation that is free from any derivatives.

This video gives an introduction to improper integrals, which arises from curves having infinite limits, and shows how to find the area under such curves.

This video shows how to obtain the integrals for basic trigonometric functions.

This video shows how to obtain the integrals for sin squared, cos squared and tan squared.

This video shows how to obtain the area between a curve and the x axis using integration and definite integrals.

This video shows how to obtain the area between a line and the curve using integration and definite integrals.

This video shows how to use integration to find the volume of a solid with a circular cross-section.

This video shows how to obtain the integrals for complicated functions by first making a substitution.
