Formulae
AS Level Mathematics A (H230)
Binomial series
^a + bhn = a n + n C 1 a n - 1 b + n C 2 a n - 2 b 2 + f + n C r a n - r b r + f + b n ^n ! Nh ,
where n C r = n C r = c m =
n n!
r r! ^n - rh !
Differentiation from first principles
f ^x + hh - f ^xh
f l^xh = lim
h"0 h
Standard deviation
/^x - x h2 / x2 / f ^x - x h2 / fx 2
= - x 2 or /f = / f -x

n n
The binomial distribution
If X + B ^n, ph then P ^X = xh = c m p x ^1 - ph , Mean of X is np, Variance of X is np ^1 - ph
n n-x
x
Kinematics
v = u + at
s = ut + 12 at 2
s = 12 ^u + vh t
v 2 = u 2 + 2as
s = vt - 12 at 2
