int_(a)^(b) (log x)/(x) dx is :

int_(-a)^(a)log((a-x)/(a+x))dx=?

int_(-1)^(1)log[(a-x)/(a+x)]dx

int(cos(a+b log x))/(x)dx

int_(a)^(b)(log x)/(x)backslash dx=(1)/(2)log(ab)backslash log((b)/(a))

If a=lim_(x rarr oo)(sin x)/(x)&b=lim_(x rarr0)(sin x)/(x) Then int_(a)^(b)(log(1+x))/(1+x^(2))dx is equal to
