@Ashwin I solved the famous Basel problem in a new different way, then I developed some of the Ramanujan's results and also developed some very nice multiple integrals.

@Chris'ssis I am sure you will do great.Keep up the hard work.
CBS Sports has this nice article explaining the origin of the word, including a newspaper snippet from 1909:
“Hand-Egg,” Not Football.

Football is certainly a misnomer, for the game is played not with the feet but with the hands, and the ball i...
@Ted student^2's goal can certainly be done... and yes, some improvement from Thursday was expected, but that's still quite a wide variance. Actually on the midterms the difference was 1-2%.
Yes, I have strange ideas, as everyone knows, lol.
Everyone knows how to solve a linear or quadratic. I don't see why we should not for the cubic and quartic as well, especially when it stops for the quintic.
we have
$\lim_{h\to 0-}\frac{\arctan\left(\frac{1}{|h|}\right)}{h}=-\infty$
and
$\lim_{h\to 0+}\frac{\arctan\left(\frac{1}{|h|}\right)}{h}=\infty$
The slope of the tangent line doesn't exist at the point $x=0$

Does anyone know what employers think of Coursera? I ask because some of the jobs I have been looking at want familiarity with R. I know how to use Python, Matlab, Mathematica, and I have played around with C but know nothing of R. So I was thinking of taking their free courses on R.
I suspect they will care more about your ability with it than your learning experience (as the second thing says). But one doesn't gain ability with a language without learning it, and Coursera seems like a good place to learn.
I want to show that $PO(1, n-1)$ acts transitively on $G^{n-1}$, where the latter is defined by $$-x_1^2 + x_2^2 + \cdots + x_n^2 = 1$$ Any ideas? It is clear that any vector in $G^{n-1}$ is space-like, but I am having trouble constructing the desired matrix.
@MikeMiller I just think the whole thing persists due to announcement bias. Coursera is a product that advertises itself as an effective way to learn things, but it didn't invent learning things, there are plenty of other ways of doing so and they all require doing the same basic thing: studying
but it's kind of like StackExchange, you gamify it in a certain way and it will be a good system for some people
@AlexanderGruber I've never used it so I can't speak to its quality or any other aspect of it. I just think that education is a mysterious beast that works differently for different people, and would tend not to make judgements that it's no better than otherwise unguided study.
heh, I have Enthusiast on meta. Maybe one day I'll get fanatic.
projecteuler.net/problem=494 I'm stuck on finding out the unique number of families of sequence prefix of length m. I know for sure if I was better at combinatorics I'd own this one. However I am stuck with doing it the long, hard way, lol
All I know is that two odd numbers cannot be in succession
and the last two numbers follow the sequence {$\dots, even, odd$}
in general you should write it down regardless of whether or not you think I'll listen; you gain by having your thoughts written down and made coherent
