Mathematics Advanced Year 11 - Module 3 - Lesson 10
Integration as Anti-Differentiation
1. Key Ideas
Differentiation tells us the rate of change of a function. But what if we know the rate of change and want to recover the original function? That process is called integration — or anti-differentiation — and it is the mirror image of everything you have learned so far.
- Integration is the reverse process of differentiation
- Why an indefinite integral includes $+C$
2. Success Criteria
By the end, you should be able to:
- Integration is the reverse process of differentiation
- The power rule for integration
- The meaning of the constant of integration $C$

5. Short Answer Questions
1. Explain this lesson goal in your own words: "Integration is the reverse process of differentiation". Use one specific example from the lesson.
2. Apply this idea to a new example: "The power rule for integration". Show your reasoning clearly.
3. Analyse why this idea matters for understanding Integration as Anti-Differentiation: "The meaning of the constant of integration $C$".
6. Extend: Apply the Idea
A student gives a memorised answer about Integration as Anti-Differentiation but does not use evidence or reasoning.
Improve the answer by writing a stronger response that uses accurate terminology, a relevant example and a clear explanation.
