The n-th derivative of the product of two functions example
Not what you're looking for?
A formula is derived for the n-th derivative of a function that is a product of two other functions, f(x)=u(x).v(x)
This formula is used to write down the n-th derivative of f(x) = e^x/(1 − x).
The proof of the result used is by mathematical induction on 'n'.

Solution Summary
The problem is solved in two stages. First a general result is proved, that of the n-th derivative of a function f(x)=u(x)v(x).
Then this formula is applied to the specific example in the question.
The result is used to write down the three first derivatives as requested in the question.
