Question:Maple 17 mtaylor not working

Hi all,

I 've been using Maple 13 and recentely upgraded to Maple 17. But the following code yielded correct results in Maple 13 but not in Maple 17( gives an error: there is no taylor series expansion, try series).

I think there is some bug or some problem with "mtaylor" of Maple 17. Can anyone verify this?

CODE:

=================

> restart;
> with(VariationalCalculus);
>
> interface(prettyprint = 3);
> with(LinearAlgebra);
>
> with(CodeGeneration);
> T := (4*(a-(1/2)*c-(1/2)*b)^2*cos((2/3)*xi*sqrt(a^2+(-c-b)*a+c^2+b^2-b*c)/r)+3*(-c+b)^2)/(4*b^2+(-4*a-4*c)*b+4*a^2+4*c^2-4*a*c);
> mtaylor(T, [a, b, c], 5);
=================

thanks,

Surani
