Second question about polynomials: assume you are given a polynomial p[x_] := c[0] + c[1] x + c[2] x^2 .... and you want to generate a polynomial p1[x] from p[x] changing one coefficient only, like: p1[x_] := -c[0] + c[1] x + c[2] x^2 Is there any other way other than the obvious CoefficientList solution?
