IsCoprime.wronskian_eq_zero_iff
∀ {R : Type u_1} [inst : CommRing R] [NoZeroDivisors R] {a b : Polynomial R},
IsCoprime a b → (a.wronskian b = 0 ↔ Polynomial.derivative a = 0 ∧ Polynomial.derivative b = 0)For coprime polynomials a and b, their Wronskian is zero
if and only if their derivatives are zeros.
