just change variables to $x=ct^2$. you don't need "integration by parts".

Take olgranpappy's advice, all you need is a simple u-sub.

Thank you, it's amazing how a simple question can transform itself into Electromagnetic Field Theory with such ease when a tired human brain is applied. Thank you again.
