Calculus 3 Lesson 61: Double Integrals in Polar Coordinates

Feb 17, 2026

Hi there! Today I have released Lesson 61 of my Calculus 3 series. In this lesson we learn about a new way to solve double integrals!

Specifically you'll learn:

  1. Why and when you will want to use polar coordinates to solve double integrals
  2. How to setup and evaluate double integrals in polar coordinates

This was a fun lesson to put together, so I hope you find it to be helpful! Next time we will look at how to find volume between two surfaces.

Until then,

- Josh
