A Level Maths Differentiation revision

Differentiation is worth more marks than almost any other topic across the three papers. Year 12 is polynomials, tangents and stationary points; Year 13 adds the chain, product and quotient rules and implicit and parametric differentiation.

Differentiation in Year 12 and Year 13

AS content is usually taught in Year 12. The full A Level adds the Year 13 content. Sitting AS exams or mocks? See the AS Level Maths checklist.

Year 12 (AS content)

  • Differentiation from first principles
  • Differentiating xⁿ; gradients, tangents and normals
  • Increasing and decreasing functions; stationary points and the second derivative
  • Simple optimisation problems

Year 13 (full A Level only)

  • Differentiating eˣ, ln x, sin x and cos x
  • The chain, product and quotient rules
  • Points of inflection and convex and concave curves
  • Implicit and parametric differentiation
  • Connected rates of change and forming differential equations

A Level Maths differentiation exam-style questions

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

Question 1easy2 marks

Find the gradient of the chord joining the points $(2, 4)$ and $(2+h, (2+h)^2)$ on the curve $y = x^2$. Simplify your answer fully.

Mark scheme: in the 7-day free trial.

Question 2medium4 marks

Find the x-coordinates of the stationary points on the curve with equation $y = x^3 - 3x^2 - 9x + 2$.

Full worked solution Free, no sign-in

  1. M1 for finding $\frac{dy}{dx} = 3x^2 - 6x - 9$.
  2. M1 for setting the gradient to zero: $3x^2 - 6x - 9 = 0$.
  3. M1 for dividing by 3 and factorising or solving the quadratic: $x^2 - 2x - 3 = 0 \implies (x-3)(x+1) = 0$.
  4. A1 for the correct x-coordinates $x = 3$ and $x = -1$.

Every question here has a full worked solution. See them all →

Question 3hard4 marks

Differentiate $y = \frac{e^{2x}}{x^2+1}$ with respect to $x$, giving your answer as a single algebraic fraction in its simplest form.

Mark scheme: in the 7-day free trial.

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.

Differentiation: common questions

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

Yes. Differentiation is part of the A Level Maths content that every board examines: AQA section G, Edexcel Pure 7, OCR 1.07. It is assessed in AQA Papers 1, 2 and 3; Edexcel Paper 1 and Paper 2; OCR A Paper 1, and the pure sections of Papers 2 and 3.

Is differentiation Year 12 or Year 13 content?

Both. The AS content, usually taught in Year 12, is: Differentiation from first principles; Differentiating xⁿ; gradients, tangents and normals; Increasing and decreasing functions; stationary points and the second derivative; Simple optimisation problems. The full A Level adds: Differentiating eˣ, ln x, sin x and cos x; The chain, product and quotient rules; Points of inflection and convex and concave curves; Implicit and parametric differentiation; Connected rates of change and forming differential equations.

What does 'differentiate from first principles' mean?

It means finding the derivative from the limit of (f(x + h) − f(x)) / h as h tends to 0, rather than using the rules. You need to show the limit step for the final marks.
