1. The problem statement, all variables and given/known data [itex]\int[/itex]|e-k|x-a||2dx 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-k|x-a||2dx =[itex]\int[/itex]|e-2k|x-a||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 |x-a| 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 eax 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.
