Calculus 3 Lesson 86: Stokes' Theorem + Mini Update

Aug 25, 2026

Hi there! Today I have released Lesson 86 of my Calculus 3 series, which is also the FINAL lesson of the series. In this last lesson we'll learn about Stokes' Theorem for solving line integrals!

Specifically you will learn:

  1. What is the formula for Stokes' Theorem?
  2. When can Stokes' Theorem be used?
  3. How to solve line integrals of vector fields using Stokes' Theorem

I hope you find this final lesson for Calculus 3 to be helpful! Thank you so much for your patience as I've worked to create these videos the last couple years. It is a relief to finally have the course complete! (Especially to have it ready in time for the Fall semester)

As for what comes next, I have not made a final decision yet. Before jumping into another major course, I will be taking some time to step back and think strategically about how I can continue growing JK Math and make the channel sustainable for the long term.

I’ve put a lot of time and energy into the videos for the channel over the years, and I want to make sure that whatever I do next allows me to keep creating helpful math tutorials for many more years to come.

In the meantime, if you are interested in supporting my work, the best way to do so (other than continuing to watch and share my tutorials!) is to join my membership site, which is linked below. If you have any questions about it, just send me an email at [email protected] and I'd be happy to answer. Thanks in advance!

Until next time,

- Josh

P.S. As with all my Calc 3 videos, there is also a bonus video for this lesson available exclusively on my membership site. You can learn how to join here.
