@SonOfNye nah, music is art - nothing wrong with people liking art (even if it really crappy art)
-
Justin Beiber's music video has over 300 million views, and something worthwhile like this struggles for 60k. 'Tis a shame.

@PedrSantiago1 yeah I was wondering about that too..
-
@ybaheti he multiplied (-1/x) and )1/x); "du" and "v", respectively.

@patrickJMT maths is an art.

I think you messed up your V in the integration by parts formula. like the uv - integral( V Du)... You put the V in ::: integral(V Du)::: as x^-2 when it should be -1/x ... right?
-
hey it doesn't change anything because ln1 = 0 but you forgot to replace x by 1 at 5:07

You are awesome. I am in differential equation, and I got stuck on this. Thank you:)

I love your step by step procedure, my teacher skips small steps which sometimes confuses me and being in the classroom setting I feel pressured to go along and not slow everyone else down

just a question..so integration by parts is not solely for product of two functions, it's also for quotient just like in your example..am i correct? thanks!:D
