Ah okay I get you. It sounds like one of the pretty standard ways of evaluating that sum, it must have come up in past papers before.

Re: MX2 Integration Marathon Find a recursion relation for the following sequence of integrals: I_n=\int e^x \sin^n(x) \, dx where n is a non-negative integer. Hence evaluate I_5.

does anyone remember the last question exactly?

be there in 5, just getting some food in me!

A reminder that you both have to add each other manually, the wii does not tell you if someone else has added you until you add him/her.

Sweet, I will be on 1ish, my FC is earlier in this thread for those who want to play. I will add everyone in this thread. We can play a couple of free for alls at the start to determine fair teams I guess, does anyone know of a quick and easy flash based chatroom on the internet to communicate...

You will want to be a little careful here, the arg of this fraction could also be -90, or even undefined (in the case z=1). This is the sort of diagram-dependence error that can be so easy to overlook. As it happens, if the arg is -90 or undefined we must still lie on the imaginary axis.

by that logic barbernators example kills all of yours.

check your wiis internet settings through the system menu, maybe the router password is wrong or something.

If people arent balanced we can play 2v2 teams with team attack on.

Fc: 3910-0275-6454

I'm okay at free for alls but I would be very impressed if one of you could beat me consistently at 1v1's.

As you get older the age range you would date gets wider. I am nearly 23 and mine is something like 20-24, mostly around 22 though. Its more maturity than age, some people are really mature for their age and others act like they are still 15.

Is an armwrestle an unfair competition because one person might have longer arms than the other? A competition obviously favours those who are better equipped to undertake them. It has a very different purpose than an exam.

The dude was more at you showering everyone with your relationship advice/expertise when you haven't been laid! Positive attitude is good.

dude.

42?

Is it stated that x is real? If not then there is a second solution.

Study won't change much, just get a good nights rest. Marks pretty much come from general aptitude / how well you can figure stuff out on the day.

Re: HSC 2012 Marathon :) You have certainly given a correct argument for why f'(0)=0. It is not obvious though why EVERY derivative of f vanishes at x=0.
