## Quick Answer

Compute symbolic partial derivatives of multi-variable functions. Select the independent variable and optionally evaluate the derivative at specific coordinate points.

## Definition

A partial derivative calculator is a mathematical utility that computes the derivative of a multi-variable function with respect to one variable while treating all other variables as constant values. It parses algebraic expressions symbolically using computer algebra systems and applies standard calculus rules. The calculator can also evaluate the resulting partial derivative at a specific coordinate point. It is widely used in physics, engineering, optimization problems, and machine learning algorithms such as gradient descent to analyze rate of change across multiple dimensions.

## How to Use

1. **Enter the expression** — Type the multi-variable function you want to differentiate in the input field.
2. **Select the variable** — Choose the target variable to differentiate with respect to from the options.
3. **Input evaluation points** — Optionally enter numeric values for each variable to evaluate the derivative at a specific point.
4. **Read the result** — View the symbolic partial derivative and the numeric evaluated result instantly.
