have you tried integrating by parts before? What have you tried for this question? :)
OpenStudy (firekat97):
It is actually my first "real" attempt lol. So what I did so far, was to let x = u and e^(6x).dx = dv then I got du = dx and v = e^(6x)/6 After that I tried subbing everything back into uv - ∫v. du and I think this is where I messed up, but I'm not too sure actually :S
hartnn (hartnn):
your steps are correct, let subb what you got \(\large x \dfrac{e^{6x}}{6} - \int \dfrac{e^{6x}}{6} dx \)
hartnn (hartnn):
good so far?
OpenStudy (firekat97):
Omg! Wait nvm, I just solved it :D silly mistake lol, but thanks so much!! :D
