Re: A Hard Math Problem

surface integrals are piss easy, there's no thought involved in any level of calculus, who are you kidding if that's mind-straining

Re: A Hard Math Problem

wrong =P

o.o It's right - the answer is 124, go look at the official AIME results

[Shashakiro]

Re: A Hard Math Problem

105, which is the answer

wrong =P

I already knew it was 124, thus my comment.

Re: A Hard Math Problem

ROFL I'm a dumbass whoops - I ****ed up the summation of the first part, that should be:

So that's (1+6+11+16+...+91+96) + (76+51+26+1) = (1 + 5 sum(i=0 to 19,i)) + (154) = 1 + 5(19)(20)/2 + 154 = 155 + 50*19 = 155 + 950 = 1105; 1105 mod 1000 = 105, which is the answer

So that's (1+6+11+16+...+91+96) + (76+51+26+1) = (sum(i=0 to 19,1+5i)) + (154) = 20 + sum(i=0 to 19,5i) + 154 = 20 + 5sum(i=0 to 19,i) + 154 = 20 + 5(19)(20)/2 + 154 = 174 + 50*19 = 174 + 950 = 1124; 1124 mod 1000 = 124, which is the answer

hahaha, sorry ^^;; I'm pretty sure I did it right on the actual AIME though :P

Re: A Hard Math Problem

blahblah apparently you never did challenging surface integrals, that or they always let you evaluate them on mathematica. when you get iterated integrals with 7th degree trig functions in them, have fun doing that by hand and telling me it is easy

Re: A Hard Math Problem

its busy work, there's no actual thought involved, just rigor

Re: A Hard Math Problem

It's true. I was quite surprised at how simple in concept flux integrals and the like were.

Re: A Hard Math Problem

well, then apparently you werent taking it in u of MN IT, cuz i got a 36 on my math subsection of ACT and i still find it difficult, either way im not out to say that one particular concept is the hardest ever, its just what were doin right now. id say most of my algorithms and data structures class is harder, especially inductive proofs, i hate them

Re: A Hard Math Problem

now im not really looking forward to the next 3 years of high school math. -_-

Re: A Hard Math Problem

ps what's "Math Analysis" o.o

Re: A Hard Math Problem

ps what's "Math Analysis" o.o

Some term he's making up to sound smart

The only analysis I know of involves lots of calculus.

[Tasselfoot]

Re: A Hard Math Problem

in my HS, Math Analysis was a fancy term for Trig.

Re: A Hard Math Problem

oh - lol, yeah one high school I went to had "PDM" or "Precalculus / Discrete Math"

Re: A Hard Math Problem

While this doesn't really contribute much to the conversation, I can't say I'm the least bit fond of mathematics. Too... consistent. Granted, that's the beauty of it, but it seems like there's never room for discussion in the idea of differing opinions, as much as right and wrong ones. What's 2+2? 4. On the moon, what's 2+2? Still 4. The Earth just imploded and we're all dead... still 4. Bah.
