Hi Rick, Square brackets around the Sin and Cos or indeed around any other function (e.g. Tan[x], ArcSin[2.0*t], f[x]) e.g. x[t_]:= 1 + Cos[2000*Pi*t] + Sin[4000*Pi*t] and vvv Plot[x[t], {t, 0, 8000*Pi}] ^^^ Yas On Thu, 1 Aug 2002, Rick Dyer wrote: > 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.
