A basic tutorial on the gradient field of a function. We show how to compute the gradient; its geometric significance; and how it is used when computing the directional derivative.
The gradient is a basic property of vector calculus. NOTE: I incorrectly write t as an angle to positive OX axis around 5 minutes. Apologies for any confusion caused.
