In[1]:=
x[t_] := 1 + Cos(2000*Pi*t) + Sin(4000*Pi*t)

In[2]:=
Plot[x, {t, 0, 8000*Pi}]

Plot::"plnr": x is not a machine-size real number at t = 
0.0010471975511965976

Plot::"plnr": x is not a machine-size real number at t = 
1019.5597016296903

Plot::"plnr": x is not a machine-size real number at t = 
2131.4776207838036

General::"stop": Further output of Plot :: "plnr" will be suppressed 
during this calculation

I am trying to plot the function x(t) defined above, same thing
happens when i try to plot other similar functions always get an error
saying that the machine size number is nor real, I have tried to find
an answer in this message group, as well as the mathematica help
online and built in, if someone knows what is going on please help me.

My computer is an AMD 1Gig with 256MG of ram, if that is of
consequence.  Windows XP pro

Any help would be appreciated

Thanks Rick
