Method (no overloads)
Summary
disc(f) with respect to mainVariable , related to the resultant
of f and its derivative by disc(f) = (-1)^(n(n-1)/2) * Res(f, f') / lc(f).
of f and its derivative by disc(f) = (-1)^(n(n-1)/2) * Res(f, f') / lc(f).
Remarks
Zero exactly when f has a repeated factor in mainVariable —
including when it has nomainVariable at all, where the
derivative vanishes and the resultant with it.
including when it has no
derivative vanishes and the resultant with it.
