Best ResponseYou've already chosen the best response.1Yes you are right @ChrisV You get \[\int\limits_{}^{} \sin (u) du = \cos (u) +C\] \[\cos(u) +C = \cos(3x^2 / 2) +C\]

Best ResponseYou've already chosen the best response.0i tend to solve for dx outright; du/6x = dx and when you sub it in the xs cancel regardless
