[SeattleScoute]

Homework Statement

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

Homework Equations

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.
