Re: Pythagorean Triangle

Hi Agnishom;

In your other thread

http://www.mathisfunforum.com/viewtopic.php?id=18119

you posted a link.

It proves there are no solutions to the diophantine equation.

with a,b,c  being positive integers by the method of infinite descent. Do you see how to apply it here?


In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
A number by itself is useful, but it is far more useful to know how accurate or certain that number is.
