Best ResponseYou've already chosen the best response.2ok, now, we change the limit, have to. tell me, if x =0, u =?

Best ResponseYou've already chosen the best response.2do you know what I am doing?

Best ResponseYou've already chosen the best response.2ok, let me explain. Originally, you have x, dx and limits respect to x then, you change (substitute) to u, so, dx must change to du and limits must follow u, right?

Best ResponseYou've already chosen the best response.0so u will be 0 too right?

Best ResponseYou've already chosen the best response.0noo is that a sqrt sign?

Best ResponseYou've already chosen the best response.2yep, from the beginning until now, we don't "substitute " that sqrt, so it's there still

Best ResponseYou've already chosen the best response.2so, what's the answer?

Best ResponseYou've already chosen the best response.0so i got (2 u^(3/2))/3+C

Best ResponseYou've already chosen the best response.2something wrong there, 1st you forgot 1/2 from du, and it cancel out with your 2/3 to get 1/3 only 2nd, it has a limits so, you have to replace those limit where you have u.
