Geogebra and the factory problem.This problem came up in another thread. 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. #2 20110606 23:52:42
Re: Geogebra and the factory problem.Hi bobbym, "Believe nothing, no matter where you read it, or who said it, no matter if I have said it, unless it agrees with your own reason and your own common sense"  Buddha? "Data! Data! Data!" he cried impatiently. "I can't make bricks without clay." #3 20110607 00:18:57

Re: Geogebra and the factory problem.Yes, and I can't imagine how difficult a polygon instead of a triangle can be!

Re: Geogebra and the factory problem.The problem that I took this one from was so artificial that one of the vertices was the answer. I mean he could solve it using a small inequality. I know solutions like that make students happy and look great in books. The fact is in the real world there might be a couple of hundred points. Often you have to settle on a solution that is good but maybe not the best. In mathematics, you don't understand things. You just get used to them.

Re: Geogebra and the factory problem.Is this still in active research or is there any good approximation algorithm?

Re: Geogebra and the factory problem.Fermat posed this problem with weights = 1 to Torricelli a long time ago. He solved it in a couple of ways. They were all geometric constructions. I feel the problem can be solved numerically but I can not find any analytical methods. In mathematics, you don't understand things. You just get used to them.

Re: Geogebra and the factory problem.Okay.

Re: Geogebra and the factory problem.Did you check for a numerical solver in Sage, all packages have them? In mathematics, you don't understand things. You just get used to them.

Re: Geogebra and the factory problem.It may be having since there are so many packages, I haven't used it yet.

Re: Geogebra and the factory problem.find_root is one command. Also Subtract from both sides. You get Multiply both sides by You get. Divide through by: 2300 You get: Now you have x on the right by itself. Do the same moves with the second equation to get a y by itself on the right. Do you follow up to here?

Re: Geogebra and the factory problem.If you look you will see that the two equations have been turned into two recurrences. They are just minus the subscripts. Tell me what you get for x and y.

Re: Geogebra and the factory problem.It will get closer and closer because this one happens to converge. Sometimes they do not and you have to pull out a different x and y.
