In a bit of overkill I have used all of these in this example Needs["Graphics`Colors`"]; Needs["Graphics`Legend`"]; f[x_] := Sin[x]; g[x_] := Cos[x]; Plot[{f[x], g[x]}, {x, 0, 2Pi}, PlotStyle -> {{Red}, {Blue, AbsoluteDashing[{5,5}]}}, PlotLegend -> {ToString[f[x]], ToString[g[x]]}, Epilog -> {Text[ToString[f[x]], {2.4, f[2.4]}, {-1,-1}], Text[ToString[g[x]], {5, g[5]}, {1, -1}]}]; Bob Hanlon Chantilly, VA USA
