I've learned that the Degree symbol somehow gets mangled when posting to
MathGroup, although it looks like a Degree sign when first posted, and
although I'm copying the Mathematica statements in InputForm. So here are
the previous statements again using an explicit 'Degree'.
Needs["Presentations`Master`"]
f[\[Theta]_] :=
5 + 2 Sin[\[Theta]] + Sin[2 \[Theta] + \[Pi]] +
Sin[5 \[Theta] + \[Pi]/4]
Draw2D[
{DrawPolarGrid[{ComplexPolar[0, 0], ComplexPolar[10, 360 Degree],
ComplexPolar[5, 45 Degree], {5, 5}}],
Red,
PolarDraw[f[\[Theta]], {\[Theta], 0, 2 \[Pi]}]},
PlotRangePadding -> 1,
PlotLabel -> f[\[Theta]],
ImageSize -> 300]
Here is 45 'degree symbol clicked from the BasicMath palette', copied in
InputForm and pasted in the message.
45 =B0
It looks ok when I paste it but I think it will get changed to '45 =B0'= by
the time it appears.
