How do I use Map for a function with two arguments?

I have a function, e.g. $T(x,t) = \exp(-t)\sin(x)$ and I want to plot, on the same, or different graphs, $T$ as a function of $x$, for an array of $t$ values.

• Search for Plot in the docs. And Table, Map or Range to build the array – Rojo Oct 27 '12 at 19:37

• You might also try things like: Manipulate[Plot[Exp[-t]Sin[x],{x,-4Pi,4Pi},PlotRange->{-E,E}],{t,-1,1}] – murray Oct 27 '12 at 19:52

Here is an approach that should work. It shows how to plot the one parameter family of functions all together or separately. Note that, although the separate plots look the same, the scales are different. Here's one way, plot T as a function of both t and x:

 Plot3D[Exp[-t] Sin[x], {t, 0, 5}, {x, -2 Pi, 2 Pi}, PlotRange -> All]


Another way is to build a function T[t] for each x, then plot the ones you want

 T[t_] := Table[Exp[-t] Sin[x], {x, -2 Pi, 2 Pi, 0.01}];
ListPlot[{T, T[0.5], T, T[1.5], T, T[2.5], T}]
