```Hi!! well, I'm using Mathematica 8 and really I need to create a legend for
especific functions where exist unkonwn range (in the above example of sin
or cos, the max and min range are -1 and 1).

The mathematica tutorials learn that for create legends in densityplot, you
can using PlotLegends where previously Needs["PlotLegends`"] is excecuted.
But it's not working.

I need you help please. Is very important solve it

Thank you for you atention
