Can someone post the collision formulas for elastic, inelastic, and perfect inelastic.
and can you express them in m1 m2 and small v for initial velocity and big V for final velocity

Hey /sci/

USAMO was today... any high-schoolfags here who took it?

ITT: Post a math problem and/or solution to a previous problem.

I am a third year math major and have decided to get serious, by this I mean ace every course I am in and totally understand and appreciate all the material.

As such I have been attempting to refine my study process, which for a long time has been poor. So I went to my universities study skills place and did a bunch of tests and scored very high on visual spatial and intrapersonal.

This is news to me, so I make the reccommended changes and wow things aren't such a grind anymore. I come to you asking for more strategies and advice on exploiting my natrual ability.

Just as an aside do you think being a primarily visiual thinker hurts math ability? I would think not but am keen to hear anyway.

>Mathematics without application is nothing but masturbation.

TONS of mathematics was done without a useful application for it and was later to found to have useful applications in the sciences. You're an idiot, don't talk about shit you know nothing about.

/sci/, I don't have money, I love math though and want to study at MIT

I'm fairly confident I could get in, I'm just stuck in the mid-tier with no financial aid but not enough money to pay, as Ivy universities have gotten to about 40-50k a year

Anyone have this same problem?

hello /sci/.

hope i get all this LaTeX shit working right.

Define <span class="math">H_0 = 1[/spoiler].
Define <span class="math">H_n = \sum_{i = 0}^{n-1} H_iH_{n-1-i}[/spoiler].
What's a closed form expression of <span class="math">H_n[/spoiler]?

(i posted this last night, but it 404'd replyless. the reason i'm reposting is i'm still curious and the original post was awkwardly worded =D )

tl;dr when's the best time to post on /sci/ to get the smart roodies?

/sci/, i figured i should finally get around to watching a lecture series on the fourier transform. from a youtube search, this appears to be the most popular: http://www.youtube.com/watch?v=gZNm7L96pfY.. what does /sci/ think? any good?

the only good math thread has 404'd
so here we go again.
post a lot of problems this tiem
