2020-07-19 18:21:45 +0200 | asked a question | What are these extra terms in symmetric polynomial calculations? I am trying to calculate the discriminant of the cubic using symmetric polynomials, here is my attempt: This gives me u: and the nice polynomial version: but I was expecting the result from here https://www.johndcook.com/blog/2019/0... I don't understand why these "e" terms exist: - 8 and why is there anything with a e[4] in it inside Thank you for any insight into this problem. |
