| Convergence pointwise and in the uniform (sup) metric | 31 Oct 2008 20:26 GMT | 11 |
I would like to check and prove or disprove the convergence (firstly pointwise and then under the uniform/sup metric) of the following two sequences of functions in the space of bounded functions from [0, 2Pi] to R=reals).

| dividing curve area in to equal parts? | 31 Oct 2008 18:29 GMT | 2 |
For given curve we can find out the area bounded by the curve using Simpson's 1/3 rule, I found out the area of the curve. Now how to divide the area in to 'n' equal parts, so that total Area=sum of n areas. Thanks.

So yeah, it's EASY to prove I'm right with non-polynomial factorization. Posters disagreeing with me can try to attack my proof, where remember THEIR argument was that 7 is split up by functions, so they want something like:

| Sinwave | 30 Oct 2008 23:10 GMT | 4 |
For different values of X, Y i.e Sin-wave would be either maximum or minimum,I plotted all the points. With the help of x values I want to find out y values. I'm thinking like this.Finding out area bounded by the wave,so with the help of 'Area' and 'x' values,finding out y values.

As I rant and rave, continually antagonize my audience, and talk about cutting public funding for basic research, or well, any research at all, I can imagine mathematicians smiling to themselves. No way people will ever listen to such nuttiness and they may smugly feel

Back when I was naive and stupid, and idealistic, I dreamed of making great discoveries to advance the state of humanity. But then I made some discoveries, got years of abuse from mathematicians, and now all I want to do is make as many academics

Why is it that every subset of a finite metric space is both open and closed? Thank you.

I am having a difficult time with this one! (10x∧3+20-8x-25x∧2) ÷ (-2x+5) I am not sure if I would swap the 20 and the 25x so that the 20 is at the end.

Um, so I've been ranting this morning as I've been feeling sorry for myself but a poster called Enrico just elevated my mood! He's shown a cool result related I think to what I call a massive theoretical super structure, which I also call a Diophantine supermap for binary ...
