A-Level Maths Formulas You Must Know
June 2026
A-Level Maths gives you a formula booklet, but it doesn't contain everything — many key results are assumed knowledge. Recalling them instantly saves precious exam time and stops you getting stuck on standard questions.
Formulas not in the booklet
You're expected to know the standard derivatives and integrals, the trig identities, the quadratic formula, and the rules of differentiation (product, quotient and chain). These come up constantly, and pausing to re-derive them costs time you don't have.
Key results to memorise
- Derivatives of xn, ex, ln x, sin x, cos x and tan x
- Standard integrals and the reverse chain rule
- The product, quotient and chain rules
- Trig identities: sin² + cos² = 1 and the double-angle formulas
- The binomial expansion
- SUVAT equations for mechanics
- The normal and binomial distribution conditions
Know how to apply, not just recite
Recalling a formula is only half the battle — you need to apply it under pressure. Practise standard question types for each result so that recognising when to use a formula becomes as automatic as recalling it.
The fastest way to memorise them
Standard results are ideal flashcard material: prompt on one side, result on the other. BrightRevision's flashcards with spaced repetition let you drill every key A-Level Maths formula and revisit the ones you keep forgetting, so they're secure by exam day.
