In other words, the determinant of a 1 by 1 matrix is the only value
which appears in that matrix.
So the dictionary of J does not allow for an interpretation other than
({.y) -: u/y when 1=#y.
Moreover, the dictionary is a reference work, not a tutorial work.
Works designed for tutorial purposes need to present concepts multiple
times, for the benefit of readers with varying backgrounds, varying
interests and varying focuses. But reference works should not need
that kind of exposition.
