What is a surface integral? (part 1) Chris Tisdell UNSW

This lecture gently introduces the idea of a "surface integral" and illustrates how to integral functions over surfaces. The idea is a generalization of double integrals in the plane.

The concept of surface integral has a number of important applications such as caculating surface area. In addition, surface integrals find use when calculating the mass of a surface like a cone or bowl.

A number of examples are presented to illustrate the ideas.

Such concepts are seen in 2nd-year university mathematics courses.
