It occurred to me that you wanted to actually mark angles on the curves or
see how the angle correlated with the two curves. The following is an
animation that marks the points on the two curves, with dim gray arrows from
the origin, and displays the value of the angle for each frame.

xyticks = CustomTicks[Identity, {-0.5, 1, 0.5, 5}];
toprightticks =

First of All, I want to thank Mr Jean Marc Guillet and Mr Bob Hanlon for
their help in my last post.
Now I need to perfom my graphic presentation by using Ticks under PolarPlot
as follow:
Needs["Graphics`"];
ShowLegend[DisplayTogether[PolarPlot[Sin[x], {x, -Pi/2, Pi/2}, PlotStyle ->
Hue[0.6]], PolarPlot[Cos[x], {x, Pi/2, 3 Pi/2}, PlotStyle ->
Hue[0.8]],
Ticks -> {{-Pi/2, 0, Pi/2, Pi, 3 Pi/2}, Automatic},
DisplayFunction -> Identity], {{{ Hue[0.6], "Sin(x)"}, {Hue[0.8],
"Cos(x)"}}, LegendPosition -> {1.1, .2}, LegendSize -> {.8, .4}}];
I need seeing in x Axe -Pi/2, 0, Pi/2, Pi, 3P/2. Please how can I achieve
this?!
Any suggestions will be very welcommmmmmmmmmmm.
Cheers.
