I= int \int_{0}^{1}log((1-x)/x)) (eq.1)
I= int \int_{0}^{1}log(x/(1-x)) {Since int_{0}^{a} f(x)dx= int_{0}^{a} f(a-x)dx}
I= int \int_{0}^{1} -log((1-x)/x)) (eq.2)
Adding eq.1& eq.2
2I=0
Therefore I=0

int_{0}^{1} means integral from zero to 1. I will unable to understand how this is to be entered in the form of maths equation and then I got no option to enter images. so sorry
