Change and approximation
Calculus studies how a quantity changes and how small changes accumulate. Graphical interpretation should accompany the notation.

Unit
The essential chapter ideas in a clear sequence before practice.
Calculus studies how a quantity changes and how small changes accumulate. Graphical interpretation should accompany the notation.
Check domain, continuity, or differentiability where required. A correct rule cannot be applied mechanically outside its conditions.
A derivative represents local rate of change and a definite integral represents net accumulation. Always reconnect the result to the original problem.
Mathematics
Follow the method step by step and check why every step is valid.
For f(x) = x³ - 3x, find the derivative and the gradient at x = 3.
Mathematics
Keep each unit in GR/DE: concept, German term, example, exercise, recap.
The structure follows the official textbook layout and is used to organise study.
f'(x) = 3x² - 3, f'(3) = 24
Before calculating, explain the key idea from “Function properties” and which conditions must be checked.
The answer should show not only which rule is used for “Function properties”, but also why it is valid here.
Analysis
Try independently, use the hint if needed, then open the answer guide.
1. Explain the idea and give one correct foundation example for “Function properties”.
Write the givens, a useful representation or rule, and only then calculate.
A complete answer defines “Function properties”, shows equivalent steps, and includes a final check.
2. Solve an application and show every intermediate step for “Derivatives”.
Write the givens, a useful representation or rule, and only then calculate.
A complete answer defines “Derivatives”, shows equivalent steps, and includes a final check.
3. Compare a correct and an incorrect approach and justify the difference for “Curve sketching”.
Write the givens, a useful representation or rule, and only then calculate.
A complete answer defines “Curve sketching”, shows equivalent steps, and includes a final check.
4. Create a short exam-style question and check your answer for “Optimisation”.
Write the givens, a useful representation or rule, and only then calculate.
A complete answer defines “Optimisation”, shows equivalent steps, and includes a final check.
The areas that usually create mistakes or need extra revision.
Where to start: textbook, daily material, PDFs, videos, and worked examples.
Targeted practice before full tests so coverage is clear.
How to measure progress in this chapter and when it enters a cumulative mock.
What to do after finishing the chapter and how it connects to the next unit.
Note: for the official examinable syllabus of each school year, always confirm with the school, tutor, and current Ministry/IEP announcements.
