Vector Calculus: Understanding the Gradient
The gradient is a fancy word for derivative, or the rate of change of a function. It’s a vector (a direction to move) that
- Points in the direction of greatest increase of a function
- Is zero at a local maximum or local minimum (because there is no single direction of increase)
