G4: Explain how to approach differentiate using the product rule in an AQA A-level Mathematics question. Your answer should identify the method, the key notation and one check on the final result.
Model answer
What a good answer should say
- A strong answer begins by recognising that this is a differentiation objective about differentiate using the product rule.
- The method is to track domain, range, composition order and inverse notation.
- The working should name the relevant notation, show one clear operation or logical step at a time, and finish with a statement that matches the question demand.
- A useful check is to substitute, compare with the graph or verify the domain/range/interval conditions where they apply.
This answer is tied to the objective: G4 Differentiate using the product rule, quotient rule and chain rule, including problems involving connected rates of change and inverse functions..
Explanation
Why this works
Use the explanation to connect the worked answer back to G4 Differentiate using the product rule, quotient rule and chain rule, including problems involving connected rates of change and inverse functions..
This question is anchored to G4 because it tests method selection and reasoning for differentiate using the product rule, not a disconnected routine skill. It rewards precise notation, visible working and a final conclusion that follows from the stated pure mathematics method.
Maths method check
