Understanding the Derivative Calculator

The Derivative Calculator is a practical tool designed to compute the derivative of a given function. Whether you're studying calculus or solving real-world problems involving rates of change, this tool makes calculating derivatives simple, while providing step-by-step solutions and visualizations.

What Are Derivatives?

A derivative measures how a function changes as its input changes. It represents the slope of the function's graph at any given point. In simple terms, derivatives help answer questions like: - How fast is something changing at a specific moment? - What is the rate of increase or decrease in a particular situation?

For example: - In physics, the derivative of a position function gives velocity. - In business, the derivative of a cost function can show the marginal cost.

Mathematically, if ( f(x) ) is a function, then its derivative ( f'(x) ) is given by: f'(x) = lim (h -> 0) [f(x + h) - f(x)] / h
