integral of exponential (Green) function with trigonometric variable












0












$begingroup$


I am searching for a tip on how to handle the following integral,
$int_c^infty exp(-x^2) sin(frac{b}{x^2}) dx$
and also
$int_c^infty exp(-x^2) cos(frac{b}{x^2}) dx$
where both c and b are real. I could not find it in the Integrals table. Thanks for having a look!

    It can expressed by the Error function

    The erfc function would in fact be the integral of the first factor, but the cosine or the sine would change that. I did not find an expression for it. Did you?
