Calculus 3 Lesson 33: TNB Frames (Frenet-Serret)

Feb 26, 2025

Hi there! Today I have released Lesson 33 of my Calculus 3 series. In this lesson we learn about TNB frames, which describe the heading, turning, and twisting of space curves!

In particular you will learn about:

  1. What are TNB frames?
  2. How to find the unit tangent, normal, and binormal vectors
  3. How TNB frames relate to curvature of space curves

This was a fun lesson to create, so I hope you find it to be helpful!

Until next time,

- Josh
