quotient rule if the two functions fx amp gx are

Question

Quotient Rule : If the two functions f(x) & g(x) are differentiable (that means the derivative exist) then the quotient is differentiable and,

                                       ( f /g)′ = (f ′ g - f  g ′ )/g ²

Note as well that the numerator of the quotient rule is very alike to the product rule so be careful to not mix the two up!
