let u = x/n ndu = dx thus I becomes I = lim(n-> ∞) n∫ sin(u) / (1 + u)^n du Using reduction.... => I = lim(n-∞) n[ - (sinu)/(n-1)(1+x)n-1 + [1/(n-1)] * [∫ cosu/(1+x)n-1 ]du Definite Function is still between 0 and ∞ for u = x/n As n -> ∞, we see that - (sinu)/(n-1)(1+x)n-1 = 0 and...

Doesn't work

I simply suck at curve sketching... i do not know why... i just suck at it.

Re: easy motion question yup, didnt read ur question properly, i missed the +1

yes yes, red lipstick is simply gorgeous

A lack of oxygen molecules, meaning the compounds created a vasely different that with enough oxygen. Ie. the burning of coal in a restricted oxygen space creates Co instead of Co2

uh... it just wants you to differentiate xlnx with respect to x Just use the product rule: Let u = x v= lnx u' = 1 and v' = 1/x Therefore d/dx (x lnx) = uv' + vu' = x(1/x) + 1(lnx) = 1 + lnx

Re: easy motion question Looks like differential equations 1. a = 2t^2 + 1 and v = 2 and x = -1 when t = 0, find x when t = 4. a = 2t^2 => dv/dt = 2t^2 ..................multiply by dt each side => dv = 2t^2 dt ....................integrate => v = t^3 + c ...................v = 2 when...

"the hsc sucks"'s BF: "Oh, gosh, the hsc sucks, do you think this nail polish maetches my stockings? the hsc sucks? heeellloooo??? Oh, gosh, your ignoring me again the hsc sucks? What did I dO?

Depends on the state of your hair. Look in the mirror and ask yourself : "Do i look like a drongo"

Re: Tattoo's how old are you? from your avatar, it seems like you're around 13/14? Getting tats huh?

is the answer: -4/(x + 1) + 3ln(x - 2) + C? Sorry, I dont have Fitzpatrick...

If you expand (3x2 + 10x -5)/(x+1)2(x-2) using Partial Fractions, you should get: 4/(x + 1)2 + 3/(x - 2)

Emo: "Look at me!! Look at me!!! I cut....my...seelf.....urrggg... (dies from blood loss).

you are not serious there are you? Coz, there this nigerian who wants me to give him my credit card details so he can protect it from criminals. he sounds trustworthy and legit. What do you think?

Ok, we went from Ex-Marines to about Speeding, how off topic can you get?

You are not supposed to rely on teachers, learn the stuff yourself. And if you aint interested, and continue to disregard the importance of your subjects, it will all come back to haunt you one day. Take a look around Bankstown station.

Girls who spend your money like you're made of it.

Through the doorways of destiny I go... What comes next, I don't really know... something something something something something something something something something something something something something something something something something something....

yes, play with them all day EDIT: whoops, i thought this was a post about clitoruses
