Best ResponseYou've already chosen the best response.0ok there's no way i can put it up like im seeing it because there's integral sign but i'll try my best...

Best ResponseYou've already chosen the best response.0first we integrate inside ignore the outside for right now

Best ResponseYou've already chosen the best response.0since we are integrating with repsect to y we treat everything thats not y ish as a constant

Best ResponseYou've already chosen the best response.0i under stand that. There's no y so I dont understand if i just put a y in there?

Best ResponseYou've already chosen the best response.0what? so you are saying you don't see the inside being 5ye^x^2?

Best ResponseYou've already chosen the best response.0no, there's not a y in the whole problem

Best ResponseYou've already chosen the best response.0whats the antiderivative of 5 with repect to x

myininaya

Best ResponseYou've already chosen the best response.0its 5x since the derivative of 5x is 5

myininaya

Best ResponseYou've already chosen the best response.0so now you understand how we got 5ye^x^2 for inner integral (we haven't used upper and lower limit yet for inner integral)

Best ResponseYou've already chosen the best response.0ok so you added a y because we were doing respect to y?

myininaya

Best ResponseYou've already chosen the best response.0yes and the derivative of 5ye^x^2 with respect to y will be 5e^x^2

myininaya

Best ResponseYou've already chosen the best response.0so the inside integral becomes (5(x/2)e^x^20)

myininaya

Best ResponseYou've already chosen the best response.0now we have the outside integral that we integrating with respect to x

myininaya

Best ResponseYou've already chosen the best response.0use a substitution for x^2

Best ResponseYou've already chosen the best response.0dont forget to put the limits in u terms

myininaya

Best ResponseYou've already chosen the best response.0so the upper limit will be 4 and the lower limit will be 0

myininaya

Best ResponseYou've already chosen the best response.0so we have int((5/4) *e^u, u=0..4)=(5/4)e^u, u=0..4= (5/4)e^4(5/4)e^0=(5/4)e^4

Best ResponseYou've already chosen the best response.0is this a 24 hour website?

Best ResponseYou've already chosen the best response.0on this problem, and when doing substitution is it always required to put the limits in u terms?

myininaya

Best ResponseYou've already chosen the best response.0i don't know. people come and go as they please. the tutors work whenever they want because we don't work for the website we work because we think its fun lol

Best ResponseYou've already chosen the best response.0if you don't put the limits in terms of u, you have to change it back to x and use the limits for x

Best ResponseYou've already chosen the best response.0is there any way you can explain that?

Best ResponseYou've already chosen the best response.0lets do an example...

Best ResponseYou've already chosen the best response.0this seems like it's going to be a really hard problem

myininaya

Best ResponseYou've already chosen the best response.0no its not hard i'm just busy doing something else at sametime

Best ResponseYou've already chosen the best response.0pretend we have int(5x,x=0..1)

myininaya

Best ResponseYou've already chosen the best response.0if we integrate this normal way we get 5x^2/2 x=0..1 = 5/2

myininaya

Best ResponseYou've already chosen the best response.0we could also do u substitution if we just wanted to for fun so let u=5x

myininaya

Best ResponseYou've already chosen the best response.0so we get int(1/5 (u), u=blah blah) =1/5 *u^2/2 let's change this back to x so we will have 1/5*((5x))^2/2 x=0..1 but we could have already done the 5x if we had used u=5x

Best ResponseYou've already chosen the best response.0is it ok to ask another question or should i just retype it on the "ask a question"? you seem to really know your stuff thats why im asking
