Re: Creating Functions?Hi; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #52 20121222 22:40:10
Re: Creating Functions?Okay, maybe it was easier than I thought to simplify, I think I figured it out. I just wasn't sure if I should distribute first or FOIL first. And what I ended up with was this: And it seems like you can divide, which seems weird, but it comes out with the right answer. So, it seems that I can divide like that, and I simplified correctly? #53 20121222 22:42:10

Re: Creating Functions?Awesome! Again thanks for your help! And I will definitely do what you suggested, I plan on devoting a lot of my time to math from here on so I'll probably be here often. #55 20121222 22:46:58

Re: Creating Functions?hi therussequilibrium Let's say you have spotted that the formula you want is Start with the next highest power of n, ie. n cubed. Write out this expression for n=1, n=2, n=3, ...n=n ............... ............ .............. ............. ............. __________________________________________________________________ Now add up each column. Most of the cube terms on the LHS cancel with most of those on the RHS. 1+1+1...+1 comes to n. The formula for the {triangle numbers} is so Rearranging multiply by 2 to remove the fraction and factorising out the common factor of (n+1) and so, finally Bob You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei
