RegionPlot[y <= (1/x^2) && y >= 0,
 {x, 1, 3}, {y, 0, 1},
 PlotRange -> {{0, 3}, {0, 1}},
 Epilog -> Text["mytext", {1.5, .8}]]

Show[RegionPlot[y <= (1/x^2) && y >= 0,
  {x, 1, 3}, {y, 0, 1},
  PlotRange -> {{0, 3}, {0, 1}}],
 Graphics[Text["mytext", {1.5, .8}]]]

=============
I would like to add text at specific (x,y) locations for a 2D graphic
generated by RegionPlot (meaning, I'd rather not use the graphic tool
and add text by hand).  Is there a way to do this?  I get mathematica
complaints that RegionPlot is not a "type of graphics."

For example, this code fails:

RegionPlot[y <= (1/x^2) && y >= 0, {x, 1, 3}, {y, 0, 1}, PlotRange ->
{{0, 3}, {0, 1}},Graphics[Text["mytext", {1.5, 1}]]

Apparently I'm using Graphics[Text[]]  incorrectly.  How can I get
such a simple function of putting text at a specific location to work
in RegionPlot?

Thanks,
Jim
