Vector reduction. The definitions have been rewritten as linear combinations of the given values:
The relative positions A & B, the components of ∡ BAC, and the ratio of radii a/b.
Tool to give the desired circle: {--link soon--}.
Although nicely dressed, I think this is a Bad Way to tackle the problem, and I will go back to projection.
