with(geometry):

eq := subs([x, y] =~ convert(Student:-LinearAlgebra:-RotationMatrix(Pi/3).<x, y>, list),
  2*(x-1)^2+sqrt(2)*y^2-1);

conic(c, eq, [x, y]);
(evala@coordinates@center)(c);
              [160/119-(72/119)*sqrt(2), -(8/119)*sqrt(3)-(44/119)*sqrt(2)*sqrt(3)]

Which should have been [cos(-Pi/3), sin(-Pi/3)].
