Q:

Re: Ratio Forumla
If you give us the answer I'll be happy to give you the equations and solve them. Interestingly, guess and check amounts to walking along a line in a plane and doing an intersection test at every point. I'll be happy to explain what I mean as soon as I know this isn't a homework problem.
