½r²θ 
 
angles in 3D vectors 
 
cosθₓ =x/|a| 
 
cosθᵧ =y/|a| 
 
cosθ₂ =z/|a| 
 
this is where vector a makes an angle θ with the x/y/z axis (because x/y/z would be the adjacent and a the hypotenuse) 
 
Expanding (a + bx)ⁿ 
 
(a + bx)ⁿ = aⁿ(1 + (b/a)x)ⁿ 
 
cosine rule 
 
a² = b² +c² -2bc cosA 
 
rule for parametric integration 
 
∫y dx = ∫(y dx/dt)dt 
 
as (dx/dt) x dt would cancel out to give you ∫y dx
