The question, in short
Work out two vector calculations: a sum of two column vectors, and a scalar multiple of a column vector.
Summarised in our own words. Use the official paper for the exact wording and any diagrams.
Part (a) · 1 mark
Add the column vectors (3, −2) and (−5, 7), giving the result as a column vector.
- 1(3 + (−5), −2 + 7) = column vector (−2, 5)
Answercolumn vector (−2, 5)
Part (b) · 1 mark
Multiply the column vector (3, −1) by the scalar 5, giving the result as a column vector.
- 1(5 × 3, 5 × (−1)) = column vector (15, −5)
Answercolumn vector (15, −5)
