What is the integral for the following equation

(e[tex]^{}ikx[/tex])/x
 
Physics news on Phys.org
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:
