Integration through approximation

  1. Jun 24, 2013 #1
    There is no analytical solution of the integral below. Can we approxiamate the analytical solution?

    [itex]\int_{k}^{K} \frac{exp(-log^2 (x))}{x(x-A)}dx [/itex]

    Is anything known about k, K, A?
    If they are given, it is easy - if not, some knowledge about them would still help.

    x = 0 and x = A have critical roles. If either is inside [k,K], you have to break the integral at that point before proceeding.

    Thanks for your replies. I am assuming x>A>0.

    My caution involves the relationship to the limits of integration [k,K].
