Calculus 3 Lesson 50: The Gradient

Hi there! Today I have released Lesson 50 of my Calculus 3 series. In this lesson we learn about gradient vectors!

In particular you will learn about:

1. What is a gradient vector?
2. An alternative formula for directional derivatives using the gradient
   
3. How to find the max/min values for a directional derivative using the gradient

I hope you enjoy this new lesson for Calculus 3! Next time we will look at how to find tangent planes and normal lines at points on surfaces with the help of gradient vectors.

Until then,

- Josh
