Product Rule 
If f (x) and g (x) are differentiable, then [ f (x) g (x) ] ' = f (x) g ' (x) + g (x) f ' (x)

Quotient Rule 
If f (x) and g (x) are differentiable and g (x) ¹ 0, then 
Power Rule 
If f (x) = x^{n}, where n is a positive integer, then f ' (x) = n x^{n1 } 
Chain Rule 
If y = f (u) and u = g (x) and both are differentiable, then
