1

length of a side on a triangle

aa = bb + cc - 2bc cos(A)

2

angle in a triangle

cos(A) = bb + cc - aa / 2bc

3

Area of a triangle

1/2 absinC
1/2 bh

4

Area of a trapezium

(a+b/2)h

5

Equation of a circle with centre (a,b)

(x-a)(x-a) + (y-b)(y-b) = rr

6

sine rule

sin(A)/a = sin(B)/b = sin(C)/c

7

differentiating from first principles

f'(x) = lim h>0 f(x+h) - f(x) / h
