Which response best matches the A-level Maths objective on construct proofs involving trigonometric functions and…?.
- A.E8: choose the method that matches Construct proofs involving trigonometric functions and…
- B.Use any familiar GCSE calculation even if it ignores Construct proofs involving trigonometric functions and…
- 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 E8: choose the method that matches Construct proofs involving trigonometric functions and….
- This option is best because state the assumption, justify each logical step, and identify the conclusion, then checks that the notation, restrictions and conclusion match the AQA A-level Mathematics objective.
This answer is tied to the objective: E8 Construct proofs involving trigonometric functions and identities..
Explanation
Why this works
Use the explanation to connect the worked answer back to E8 Construct proofs involving trigonometric functions and identities..
E8: choose the method that matches Construct proofs involving trigonometric functions and… is the correct option. It directly supports construct proofs involving trigonometric functions and… by requiring the student to state the assumption, justify each logical step, and identify the conclusion.
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: recall.
- Check the operation, notation, units, and final answer form against the question before moving on.
