Can't integrate the "e"s here 1. The problem statement, all variables and given/known data [tex]\int 2/e3x(6+e-3x)dx[/tex] 2. Relevant equations I have no idea as to what equations to use, other than [tex]\int[/tex] e[tex]u[/tex] du = e [tex]u[/tex] + C 3. The attempt at a solution [tex]\int[/tex] 2/(6e3x +1) dx u = 6e3x +1 du = 18e3x dx and that's as far as I can get, I can't think of what else to do. HELP!! Thanks in advance.
