When k approaches 1, one frequency tends to infinity but the other
tends to Fo/SQRT2 (derived from Fo/SQRT(1+k)). That is because the
primary cap transformed by the inverse turns ratio squared appears in
parallel with Cs (and the inverse also applies). The net result is a
single frequency which is not Fo.
