WebIn most induction proofs we start with a base case of n = 1, then assume N = n works, then apply N + 1, and usually make use of the assumption to get a statement that is TRUE to prove it. Here is the function: f ( x) = ln ( 1 + x). And here is the equation we wish to apply Induction to: f ( n) ( x) = ( − 1) n − 1 ( n − 1)! ( 1 + x) n.
