Convergent series for Exponential integral
Posted:
Jul 22, 2008 12:29 PM


Hi I need a little help here. I have a function,
f = exp (i*k*sqrt(x^2+a^2)) / sqrt(x^2+a^2).
I need to integrate this function with respect to x. As this is an exponential integral, exact integral is not possible. what could be the convergent series for this?
