Homework Help: Simplify function

mkeg1 · Sep 27, 2010

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

Started at (x * x/sqrt(1+x^2))/sqrt(1+x^2)-1

2. Relevant equations

3. The attempt at a solution

now im at

(x^2 (1 + x)^(1/2) - x^2)/(1 + x)^(1/2)

I am stuck on how to simplify further

Your simplification looks wrong, unless I'm reading the problem incorrectly.

(x * x / sqrt(1+x^2)) / sqrt(1+x^2)-1
x^2 * (1+x^2)^-1/2 * (1+x^2)^1/2
Can you go on from there?
