You get a formula sheet in the exam. It has:
Volume of a sphere
Surface area of a sphere
Volume of a cone
Curved surface area of a cone
Area of a triangle using 1/2 ab sinC
Sine rule
Cosine rule (both re-arrangements, to find an angle or a side)
The regular form for a quadratic equation
The quadratic formula
The trig identities:
tan x = sin x / cos x
sin^2 x + cos^2 x = 1
(Note that for the 2nd trig identity, no re-arrangements are given)
The formula sheet can be viewed on the 2nd page of the paper and is online with the sample papers / past papers. The specification is on the AQA website. On TES someone posted a topic list I think. I recommend using GetRevising resources, YouTube and Mr Barton Maths website for help remembering / practising these.
WHAT YOU WILL NEED TO REMEMBER THAT'S NOT GIVEN:
Pythagoras's theorem
SOHCAHTOA
Trig graphs
Linear / Circle / Quadratic graphs
Completing the square
Trig values (This may come up multiple times)
Matrix multiplication (for 2x2 and 1x1 matrices)
Matrix transformations (Enlargements, reflections and rotations)
Fractions / Decimals / Percentages / Ratios
Functions (including domain and range)
Pi formulas and cylinders
Pythagoras / Trigonometry in 3d
Algebraic Fractions
Inequalities
Algebraic / Geometric proofs (including circle theorems)
1st and 2nd derivative (dy/dx and d^2y/dx^2)
Changing the subject of a formula)
Algebraic sine/cosine rule (including proofs)
Factorising (where a > 1 or with 2 unknowns)
Angle against a plane
Factor theorem
Sketching graphs with minimum / maximum / inflection points)
Simultaneous equations
Don't worry though, it's unlikely that this will all come up.
Good luck for Thursday's exam
