Master AQA Maths Calculus using simple revision notes, key facts and practice questions — all generated by AI for your exam.
Calculus is a branch of mathematics that deals with rates of change and the accumulation of quantities. It is divided into two main areas: differentiation, which focuses on finding the rate of change of a function, and integration, which is concerned with finding the area under a curve.
Key Concepts
- 1Differentiation is used to find the gradient of a curve at a point.
- 2Integration calculates the area under a curve or the accumulation of quantities.
- 3The Fundamental Theorem of Calculus links differentiation and integration.
- 4Common rules of differentiation include the power rule, product rule, and quotient rule.
- 5Integration techniques include substitution and integration by parts.
Simple Explanation
Calculus helps us understand how things change and how to calculate areas. When we differentiate a function, we're finding out how steep it is at any point, while integration helps us add up small pieces to find a total area. Think of it as measuring how quickly something is moving and how much space it covers.
Memory Trick
“Remember 'D for Derivative, I for Integral' – Derivatives deal with change (like speed), and Integrals deal with accumulation (like distance).”
