Answer 4

The Quotient Rule says, that if you have 2 functions, f(x)/g(x), its deriavtive will be:

[g(x) f '(x) - f(x) g ' (x)]/[g(x)^2]

Answer 5

f(x)=U.V --> f'(x)=U'V+V'U

Answer 6

f(x) = sin x f ' (x) = cos x
g(x) = x g ' (x) = 1

So the derivative of f(x)/g(x) = ?

Let me see you substitute into the formula.
