How Triangle Solvers in Teaching Code Handle the Ambiguous Case of the Law of Sines
A research poster from the School of Continuous Improvement mines 417 triangle-solving functions from public repositories of course notes and worked solutions and tests each against an exact oracle on 20,000 side-side-angle inputs. Most take a single arcsine and stop, 96 of them after naming the ambiguous case in a comment; every solution strategy fails at the right-angle boundary, and the poster releases a five-input test fixture that would have caught each failure class observed.
