Calculus 3 Lesson 77: Line Integrals of Vector Fields

Jun 16, 2026

Hi there! Today I have released Lesson 77 of my Calculus 3 series. In this lesson you'll learn about line integrals of vector fields!

In particular you will learn:

  1. What the line integral of a vector field represents
  2. How to setup and evaluate line integrals when given a path and a vector field (2D & 3D)

I hope you enjoy this new lesson for Calculus 3! Next time we will look at another form of line integrals that you may encounter that are important to be able to solve (differential form!)

Until then,

- Josh
