It doesn't take a degree in mathematics to know that as Vr---> ∞,
Vo in your equation approaches zero, not c.

C'est pourtant très simple.
What is très simple is that the speed of light is measured as c,
not infinity. In four-vector SR, a "four-velocity" is presumed
which is v/sqrt(1 - v^2/c^2), but I look upon it as an affectation.
