Evaluate the following integrals:
For x=1, equation: 0 = A+B
For x=1/e, equation: -1 = B i.e. B = -1
So, A = 1
The given equation becomes
Tip – If f1(x) and f2(x) are two functions, then an integral of the form can be INTEGRATED BY PARTS as
where f1(x) and f2(x) are the first and second functions respectively.
Taking f1(x) = 1/(1+logx) and f2(x) = 1in the second integral and keeping the first integral intact,
, where c is the integrating constant
