In mathematics, the derivative is a fundamental tool that
quantifies the sensitivity of change of a function's
output with respect to its input.
The derivative of a function of a single variable at a chosen
input value, when it exists, is the slope of the tangent line
to the graph of the function at that point.

A derivative is a fundamental concept in calculus that describes how a function changes in relation to its independent variables. In simplest terms, the derivative measures the rate of change or slope of a function at a specific point.
