    Please formulate carefully. Integral over k or x? Between what limits?

    k is a constant. x a variable.

    I figured out the answer. It's the imaginary argument of the exponential integral.

    Glad you figured it out, I'm still guessing at what you mean :smile:
    For I don't see an integral and if I add one, it doesn't evaluate to k x.

    Sorry Chip, but instead of writing the sign for integral I simply stated that I was looking for the integral. My assumption was that you'd understand what that implied, i.e.,

    [tex]\int[/tex](e[tex]^{}ikx[/tex])/x dx

    where k is a constant.

    The answer is can be found at the following:


    under the subheading "Exponential integral of imaginary argument"

    Best :cool:
