Calculus 3 Lesson 52: Extrema & Critical Points in 3D Space
Oct 24, 2025Hi there! Today I have released Lesson 52 of my Calculus 3 series. In this lesson we learn about extrema and critical points in 3D space!
In particular you will learn about:
- How to identify extrema in 3D graphically
- How to find critical points for multivariable functions
I hope you enjoy this new lesson for Calculus 3. Next time we will look at a method for determining if critical points are relative extrema or saddle points without the need for a graph of a surface!
Until then,
- Josh
