Use Evaluate
In[7]:=
Plot[Evaluate[Table[Normal[Series[Sin[x], {x, 0, i}]], {i, 5}]], {x,
-15, 15}, Frame -> {True, True, False, False},
Axes -> False, FrameLabel -> {"x", ""}];
Plot has the Attribute HoldAll.
As Help Browser mentions if Plot is used to plot a list of functions,
that list should appear explicitly as the first argument in Plot or
should be introduced using Evaluate or other means.
In[8]:=
Attributes[Plot]
Out[8]=
{HoldAll, Protected}
The same holds true for e.g. NIntegrate
In[10]:=
NIntegrate[Evaluate[Table[Normal[Series[Sin[x], {x, 0, i}]], {i, 5}]],
{x, -2, 10}]
Out[10]=
{48., 48., -368.0000000000001, -368.0000000000001, 1020.8000000000009}
In[12]:=
Attributes[NIntegrate]
Out[12]=
{HoldAll, Protected}
But e.g.
In[1]:=
Integrate[Table[Normal[Series[Sin[x], {x, 0, i}]], {i, 5}], {x, -2,
10}]
Out[1]=
{48, 48, -368, -368, 5104/5}
In[2]:=
Attributes[Integrate]
Out[2]=
{Protected, ReadProtected}
