Obviously, at this point x is 0

So the final limit is ln1 and 0

That is true.

Because the integrand is an odd function, it must be an even function after integration, and the even function has f(x)=f(-x), and if the upper and lower limits of the integral are a and -a, respectively, then there must be: f(a)-f(-a)=f(a)-f(a)=0
