Hi,

it can't work, because you have not given a number n
so you have to define

Grafico[n_] :=
  Plot[{F, Taylor[n]} // Evaluate, {x, -Pi, Pi},
   DisplayFunction -> $DisplayFunction]

and

type

Grafico[4]

or with Mathematica 6.0

Manipulate[
  Plot[{F, Taylor[n]} // Evaluate, {x, -Pi, Pi}], {n, 0, 64, 1}]

Regards
   Jens
