You've elegantly transformed the 1-dimension(2 parameter) problem into
a 2-dimension(1 point) problem. Bravo! What a great perspective
change from which to view the solution space.
This kind of side-ways thinking is why I love following these kinds of
discussions, and why I'm so often surprised at how simple (or hard) a
problem can become when a separate perspective is taken.
Thanks for the paradigm shift!
