CR MEI A-Level Mathematical Formulae
with correct answer 2025/2026O
(a^x)^y - a^xy
a^x * a^y - = a^(x+y)
a^x / a^y - a^x-y
Arc length (angle is in RADIANS) - s=rθ
Area of a circle - πr²
Area of a sector (angle is in RADIANS) - A = 1/2 r^2 θ
Area of a trapezium - 1/2(a+b)h, where a and b are the lengths of the parallel sides and h is their
perpendicular separation.
