A Level Maths Vectors revision

Vectors in A Level Maths are about geometry and forces rather than equations of lines (that is Further Maths). Year 12 works in two dimensions; Year 13 extends to three.

Vectors in Year 12 and Year 13

AS content is usually taught in Year 12. The full A Level adds the Year 13 content.

Year 12 (AS content)

  • Vectors in two dimensions: column vectors and i, j notation
  • Magnitude and direction; unit vectors
  • Adding vectors and multiplying by a scalar; position vectors and distances
  • Using vectors to solve geometric problems

Year 13 (full A Level only)

  • Vectors in three dimensions, using i, j and k
  • Position vectors and geometric problems in 3D

Worked examplemedium3 marks

Given that the magnitude of the vector $4\mathbf{i} + k\mathbf{j} - 2\mathbf{k}$ is $6$, find the possible values of the constant $k$.

Mark scheme and worked answer
  1. M1 for setting up the magnitude equation: $\sqrt{4^2 + k^2 + (-2)^2} = 6$.
  2. M1 for squaring both sides and simplifying: $16 + k^2 + 4 = 36 \implies k^2 = 16$.
  3. A1 for finding both possible values: $k = 4$ and $k = -4$.

Vectors on the AQA, Edexcel and OCR papers

Every board examines the same A Level Maths content, set by the Department for Education. Only the paper it appears on and the section numbering differ.

Practice questions

A Level Maths vectors exam-style questions

Three examples from the question bank. Every question comes with a step-by-step mark scheme (M, A and B marks) once you start practising.

Question 1easy2 marks

Find the exact magnitude of the vector $\mathbf{a} = 3\mathbf{i} - 4\mathbf{j} + 12\mathbf{k}$.

Question 2medium2 marks

Find a unit vector in the direction of $2\mathbf{i} - 2\mathbf{j} + \mathbf{k}$.

Mark scheme: in the 48-hour free trial.

Question 3hard5 marks

The vertices of a triangle are $A(1, 0, 0)$, $B(0, 1, 0)$, and $C(0, 0, 1)$. Find the exact area of the triangle.

Questions are original and written in the style of Edexcel 9MA0, and cover content that AQA and OCR examine too. They are not past-paper questions.

Vectors: common questions

Is vectors on the AQA, Edexcel and OCR A Level Maths exams?

Yes. Vectors is part of the A Level Maths content that every board examines: AQA section J, Edexcel Pure 10, OCR 1.10. It is assessed in AQA Paper 1, and Section A of Papers 2 and 3; Edexcel Paper 1 and Paper 2; OCR A Paper 1, and the pure sections of Papers 2 and 3.

Is vectors Year 12 or Year 13 content?

Both. The AS content, usually taught in Year 12, is: Vectors in two dimensions: column vectors and i, j notation; Magnitude and direction; unit vectors; Adding vectors and multiplying by a scalar; position vectors and distances; Using vectors to solve geometric problems. The full A Level adds: Vectors in three dimensions, using i, j and k; Position vectors and geometric problems in 3D.

Is the scalar product in A Level Maths?

No. The scalar (dot) product and vector equations of lines are in A Level Further Maths, not A Level Maths. A Level Maths needs magnitude, direction, position vectors and geometric problems in 2D and 3D.
