Re: Several functions in a single 2D-plot

?Plot
Plot[f, {x, xmin, xmax}] generates a plot of f as a function of x from
xmin \
to xmax. Plot[{f1, f2, ... }, {x, xmin, xmax}] plots several functions
fi. More...

For example,

Plot[ {BesselJ[0,x],BesselJ[1,x],
      BesselJ[2,x] },
{x,0,10},PlotStyle\[Rule]{Thickness[0.008],Thickness[0.\
                  006],Thickness[0.004]}];

or

g={BesselJ[0,x],BesselJ[1,x],BesselJ[2,x]};

Plot[Evaluate[g], {x, 0, 10}, PlotStyle -> {
    Thickness[0.008], Thickness[0.006], Thickness[0.004]}];

Of course, after you can change the default options and add legends to
make the plot look better.

For example,

Plot[ {BesselJ[0, x], BesselJ[1, x], BesselJ[2, x] }, {x, 0, 10},
        PlotStyle -> {AbsoluteThickness[1], AbsoluteThickness[
      2], AbsoluteThickness[3]}, TextStyle -> {FontFamily -> "Times", \
FontSize -> 20}, AxesLabel -> {"x", TraditionalForm[BesselJ[n,
         x]]}, PlotLegend -> {"n=0", "n=1", "n=2"},
    LegendShadow -> None, LegendPosition -> {0, 0}, ImageSize -> {500,
300}];

Cheers,

Jim
