multivariable polynomials |
Hi, I'm using pari-2.1.4 to work with two-variable polynomials, and I got a strange result: ? f = x^5 - y^234*x^2 - 3*y^7 %1 = x^5 - y^234*x^2 - 3*y^7 ? f % (x^3-1) %2 = (-y^234 + 1)*x^2 - 3*y^7 ? f % (y^3-1) %3 = 0 In order words, I cannot "mod y" ! Is that because pari can only hand polynomials with x as the variable? Many thanks! Best, Siman Wong
