1. The problem statement, all variables and given/known data
[itex]\int[/itex]e^{kxa}^{2}dx This integral is from inf to +inf 2. Relevant equations A table of integrals would seem to be needed. 3. The attempt at a solution [itex]\int[/itex]e^{kxa}^{2}dx =[itex]\int[/itex]e^{2kxa}dx from here it would seem to simplify down to a variation on the theme of [itex]\int[/itex]e^{ax}dx where a would be 2k and x would be xa but I'm not sure. Two basic questions come to mind right away: a) am I on the right general track? and b) looking through a standard table of integrals there is plenty on the integral of e^{ax} but no mention of the integral of e^{ax} which leads me to think there's something deeper here that I'm failing to grasp.
