Exam-style question
Try this first
Add the two-dimensional vectors (1, 2) and (3, 4). Show your working one step at a time.
Model answer
What a good answer should say
- The final answer is (4, 6).
- Use vector component addition for the two column vectors.
- Add the horizontal components: 1 + 3 = 4.
- Add the vertical components: 2 + 4 = 6.
This answer is tied to the objective: J4 Understand and use position vectors; calculate the distance between two points represented by position vectors..
Explanation
Why this works
Use the explanation to connect the worked answer back to J4 Understand and use position vectors; calculate the distance between two points represented by position vectors..
exam warm-up keeps the canonical answer (4, 6) fixed before the model answer is written, so the worked solution and final answer agree.
Maths method check
- Topic focus: Pure Mathematics - vectors.
- Question style: exam_style.
