hi alls i dont really understand why these "Manipulate" do not work :
Clear[n]
g[x_] = Series[x/Sqrt[1 - x^2], {x, 0, n}]
gg[x_] = Normal[g[x]]
Manipulate[gg[x], {n, 1, 5}]
Manipulate[Plot[gg[x], {x, -1, 1}], {n, 1, 5}]
And if i replace the first line with :
g[x_] = Series[x/Sqrt[1 - x^2], {x, 0, n}]/.n->2
then the g[x_] works, but then n seems to remain fixed to 2 If anyone can clear me...
