Man, Thanks for the video... I have a midterm next monday and it is really helpful! One quick question, why didn't you replace the 1/x and the 1/v at the minute 5:30, I couln't undestand how did you "eliminate" them.
@@chandnimohammad9260 He didn't show the step of finding du. In order to get du, you have to take the derivative of u with respect to x. So if u = (ln(x)-µ)/v then du = dx/(xv). Then we can replace dx/(xv) with du when we rewrite the integral in terms of u. Hope this helps :)
Mancinelli's Math Lab gotcha, great videos though! That's a long proof to chug through! I'm also taking the last sitting of MFE here in a week or so, best of luck to both of us!
Tk Mcwhertor going great, I love it! Really busy though, working full time while studying for exams. Definitely pays off though, well worth the effort!
