These techniques match the SEAB GCE O-Level Additional Mathematics (4049) syllabus: product, quotient, chain, and implicit differentiation in radians.

The core idea is simple: Differentiation techniques help when the expression is not a simple power.
Use it as a working check: Identify the structure first: product, quotient, chain, or implicit relation. Choosing the rule is half the question.
Then go one layer deeper: Example: for (3x^2 - 1)(2x + 5), use product rule; for (5x^2 - 3x + 1)^(4/3), use chain rule.
Choosing the differentiation rule
Do not choose a rule by looking for the first symbol you recognise. Rewrite the expression lightly, then decide which structure is actually controlling the derivative.
