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

$\int -1 to 1 log((2-x)/(2+x)) dx$

2. Relevant equations

3. The attempt at a solution

okay so normal attempt at integration wont work coz then we get log 1
what am i supposed to do i tried applying some general formulas of definite integral but i dont seem to get the answer

Can you show what you did using normal integration? I actually don't think log(1) is really wrong. But how did you get it?

This logarithmic identity should get you going:

$log\frac{a}{b} = log(a)-log(b)$

I agree with Dick though, you have the correct answer.
