What is the formula for finding acceleration? (When under constant acceleration)
a = (v-u)/t
What is the formula for finding displacement? (When under constant acceleration)
s = 1/2 (u+v)xt
What is the formula to find displacement when the final velocity is unknown? (Under constant acceleration)
s = ut + 1/2(at)^2
How do you find velocity^2 when the time is unknown? (Under constant acceleration)
v^2 = u^2 + 2as
What are the 2 key formulas to find variable acceleration?
v = ds/dt
And
a = dv/dt
How do you find the area of any triangle?
1/2ab x SinC
What is the Cos rule to find a side in any triangle?
a^2 = b^2 + c^2 - 2bc x CosA
What is the Cos rule for finding an angle in any triangle?
CosA = (b^2 + c^2 - a^2)/2bc
What is the Sin rule to find a side in any triangle?
a/SinA = b/SinB = c/Sin C
What is the Sin rule to find an angle in any triangle?
SinA/a = SinB/b = SinC/c
What are the the rules for Sin, Cos and Tan in right-angled triangles? SOHCAHTOA
Sin = opposite/hypotenuse
Cos = adjacent/hypotenuse
Tan = opposite/adjacent
What is the formula for binomial expansion?

What is the binomial distribution formula?
X~B (n,p)
n = number of trials p = probability of success
