# How to Plot several functions using differents colors , It is possible to use TeX or MathSymbols?

The question is to plot several functions with different colors. Using a Table, which contains important information into it.

You can see in the example above three functions with different values for each graph. However, in this example, all the curves are blue, I would like to show them differently.

Also, I would like to add it a caption, titles in Latex, i.e, superscript, vectors, etc. but it doesn´t work well.

Of course, after using the basic Math assistant but it does not work properly The output is wrong, (for example, something like that \vec{f}_x to call the function complaining. Here it is the code and the plot; Clear["Global*"];

L = 15; pp = 100; k = 1;
v[x_] = {Sin[( n + 1) k  x], Cos[ n  k  x],   x Sin[n x k]}  ;

graf1 = Table[Plot[v[x], {x, -L, L}, PlotRange -> Full], {n, 0, 2}];

FontSize -> 12] & /@ {X, Y, Z },
TextCell[StringJoin[{"n = ", ToString@#}], FontSize -> 12] & /@
Range[0, 3]}, TableAlignments -> Center, TableSpacing -> {1, 1}]

• I do not understand what the question is here. Please rephrase it. Make sure it is clear, concise, unambiguous, and most importantly: there is an explicitly stated and focused question. – Szabolcs Jul 8 '19 at 6:51
• You can see that each panel have three different plots, How to put each one using a different color (Black, red, Brown). and how to add Latex Symbols in the caption? – irondonio Jul 8 '19 at 8:15
• Please separate unrelated questions. The plotting one has been asked many times, see e.g. mathematica.stackexchange.com/q/1731/12 The LaTeX one I still do not understand. Please show a concrete example: this is what I tried, this is what happened, this is what I expected to happen instead. – Szabolcs Jul 8 '19 at 8:39
• Of course, I reviewed all of these examples them, It does not work for this case. Try to run the code before to write an incorrect answer here – irondonio Jul 8 '19 at 8:47
• If you add //Evaluate as in graf1 = Table[ Plot[v[x] // Evaluate, {x, -L, L}, PlotRange -> Full], {n, 0, 2}] ? – chris Jul 8 '19 at 8:49

graf1 = Table[
