Another Matematical Induction Problem

[SeattleScoute]

1. The problem statement, all variables and given/known data

Prove by incuction that for all positive intergers 1/(n(n+1)=(n/(n+1)


2. Relevant equations



3. The attempt at a solution

I have proved this is true for n=1. I need to find a way to set the equation for n+1

Welcome to physicsforums(=

does it holds for all positive integer?
can you check for some case like positive integer 5 .

\frac{1}{5(5+1)}\neq\frac{5}{5+1}

Are you sure you have given us the problem exactly as stated. icystrike gave a counterexample to show that the equation above isn't generally true.

Note that you are missing two closing parentheses, that suggests something can be wrong with the equation.
