integral from 0 to 3 5x Sin (3x+1)
I'm pretty sure this is an integration by parts. I made U 5x and dv = sin (3x+1). Is this the correct path?

Best ResponseYou've already chosen the best response.0By parts should work, u = 5x, dv = sin(3x+1) so now integrate for v

Best ResponseYou've already chosen the best response.0so would v end up being \[\frac{ 1 }{ 3 } \sin (3x+1) \] sorry for the dumb question. Been a couple of years since Calculus 1!
