Re: classify

Hi;

What point?


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.

Re: classify

You can also get the answer algebraically without resorting to a graph.
