The forward difference quotient is a method for approximating the derivative of a function at a specific point by using the difference between function values at that point and a slightly forward point. It serves as a fundamental tool in numerical differentiation, providing a simple way to estimate the rate of change when analytical differentiation is impractical.

Numerical differentiation is a technique used to approximate the derivative of a function using discrete data points, often necessary when an analytical form of the derivative is difficult or impossible to obtain. It is widely used in scientific computing and engineering to solve problems involving rates of change, but care must be taken to manage errors that arise from discretization and finite precision arithmetic.

The rate of change quantifies how one quantity changes in relation to another, often represented as a derivative in calculus. It is a fundamental concept in mathematics and science, used to understand dynamic systems and model real-world phenomena.
