second order functionsHey guys. #3 20051214 07:50:55
Re: second order functionsIt just means you multiply x times b "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #4 20051214 08:33:37
Re: second order functionsif the equation is x^2 + bx = 0, then b is the negative location of the second root (the first being 0). In other words, b is a root of the equation. "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #5 20051214 09:28:37
Re: second order functionsThe larger b is, then the parabola is bent more upward as you go right? igloo myrtilles fourmis #6 20051214 11:06:20
Re: second order functionsYou're thinking of when it is something like bx². Why did the vector cross the road? It wanted to be normal.
