Answer 2

\[u=\ln(x)\]

get a new integral ...then do parts

Answer 3

I make a sub first then I try integration by parts, but i keep on going in circles. ill either get cos(n)e^n or -sin(n)e^n where n= lnx. but the integrand keeps going in circles.....

Answer 4

so parts twice...then you can solve for the integral

Answer 5

*do parts twice...
