Topic: The Gradient Vector vs. The Directional Derivative

50-minute video walkthrough with a PDF for you to take notes on as you watch the video! Follow along, take notes on the provided PDF, work through examples with me, and learn about the gradient vector and the directional derivative (two common vector calculus topics.)

What's does the gradient vector of a function find for us? What does the directional derivative find for us? How are they related?

Let's sort out some confusion about the gradient vector and the directional derivative! I will explain what each one of them is, what exactly they tell us about a function, and help clarify confusion about the two different topics.
