# Partial Derivatives and Gradients

Learn about partial derivatives and how to calculate the gradient of a multivariate function.

## We'll cover the following

## What are gradients?

A **multivariate function** in mathematics is a function that takes more than one input variable and produces one or more output variables. For example, the volume of a cylinder

For multivariate functions **gradient**. The gradient is a collection of quantities known as partial derivatives*. *

**Partial derivatives** are useful for multivariate functions, such as the volume of a cylinder, because they can help us understand how the volume changes when one of the variables (radius or height) changes while the other is fixed.
