Below is the general case submitted by Roland Sampy.

There seems to be at least 2 expressions for

We had a solution, but it looked a little clumsy. Moreover, we lost it :)

So, do help us to recover... Oh yes, do enjoy as well...

ReplyDeleteEach value of a < 2 and b <2 we have 2 positions of C and 2 positions of B.

So r is not only depend on a and b but also depend on position C relative to B .

Sounds correct. In that case the final expression for r

ReplyDeleteshould give two separate roots. (Most likely quadratic)
