 Author Comment/Response Gideon 11/28/07 11:11am Hi All! I wonder if you could elucidate a result Mathematica 6.0 returns when calculating the eigenvalues of a certain 3x3 symbolic matrix. One such root (out of possible three) has the explicit form: Root[#1^3 + #1^2 (-Subscript[c, 1] - 2 Subscript[c, 2] - 2 Subscript[c, 3]) - Subscript[c, 1] Subscript[c, 2] Subscript[c, 3] + #1 (Subscript[c, 1] Subscript[c, 2] + 2 Subscript[c, 1] Subscript[c, 3] + 3 Subscript[c, 2] Subscript[c, 3]) &, 1]. What does #1 mean here? Does Mathematica mean here by Root that it has yet to actually solve the equation? How can I instruct it to solve each equation, substituting for #1 a more seemly variable such as x? Why does it not simply solve symbolically the resulting eigenvalue equation when I use the function Eigenvalues[]? Thanks a million, Gideon URL: ,
