What's the difference in all the polynomial solve/root/zero functions?
Hello,
I am confused by why the Prime has so many different menu options for solving polynomial roots. They all seem conceptually identical to me. Toolbox / CAS / Solve / Solve > solve() Toolbox / CAS / Solve / Zeros > zeros() Toolbox / CAS / Solve / Complex Solve > csolve() Toolbox / CAS / Solve / Complex Zeros > cZeros() Toolbox / CAS / Polynomial / Find Roots > proot() Although the syntax in the last (proot) is slightly different from the first four, and some return {} lists while others return [] vectors, all five functions yield identical answers when you feed them the polynomial x^4 1 = 0 > {1, i, 1, i} or [1 i 1 i] Can someone offer any insight into when you might need to select one over the others?
