What is the safest exam approach for evaluate definite integrals?.
- A.H3: justify each step using the relevant integration rule
- B.Use any familiar GCSE calculation even if it ignores Evaluate definite integrals
- C.Write only the final answer without showing the mathematical method
- D.Change the notation or restrictions to make the algebra look simpler
Model answer
What a good answer should say
- The correct answer is H3: justify each step using the relevant integration rule.
- This option is best because identify the mathematical structure, choose a valid method, and justify the final statement, then checks that the notation, restrictions and conclusion match the AQA A-level Mathematics objective.
This answer is tied to the objective: H3 Evaluate definite integrals; use a definite integral to find the area under a curve and the area between two curves..
Explanation
Why this works
Use the explanation to connect the worked answer back to H3 Evaluate definite integrals; use a definite integral to find the area under a curve and the area between two curves..
H3: justify each step using the relevant integration rule is the correct option. It directly supports evaluate definite integrals by requiring the student to identify the mathematical structure, choose a valid method, and justify the final statement.
The other options are weaker because they hide the reasoning, ignore restrictions, or use a generic calculation that may not fit the objective.
Maths method check
- Topic focus: Pure Mathematics.
- Question style: practice.
- Reasoning demand: understanding.
- Check the operation, notation, units, and final answer form against the question before moving on.
