Calculus 3 Lesson 85: Divergence Theorem

Aug 18, 2026

Hi there! Today I have released Lesson 85 of my Calculus 3 series. In this lesson we learn about the Divergence Theorem!

Specifically you will learn:

  1. What is a simple closed surface? 
  2. How to use the Divergence Theorem to find flux of surfaces bounding solid regions

I hope you enjoy this new lesson for Calculus 3! The next lesson will be the final lesson of Calculus 3, where we will learn about one more method for solving line integrals with the help of a surface integral!

Until then,

- Josh
