Differentiation

Differential calculus is the area of mathematics concerned with describing and analysing change. It provides tools for measuring how one quantity varies in response to another, allowing us to explore rates of change, growth and decay, and how functions behave locally. It focuses on calculating the derivative, a measure of how a function is changing at any given point. The derivative gives the slope of the tangent line to a curve, capturing its immediate direction and steepness.

Differential calculus underpins many real-world applications. It helps us understand motion by relating position, velocity and acceleration, allows us to model biological and chemical processes that grow or decay, supports optimisation in business, engineering and data science and it provides insight into how systems respond to changes in inputs or external conditions.

This resource revises differentiation and within differentiation there are 7 key concepts:
