Hey there all,

I am using RMagick to draw some circles.

what i need though is a math formula to give me a pair of plot points

for an angle.

Say a circle is 40 x 40 on a sheet of graph paper.

this would put the center of the circle at x=20, y=20

and it would make the radius = 20.

now, i need to be able to pass in a number like say, 20 degrees and

return the x and y plots of this on the circle.

i know, more a math problem than ruby, but i could use any suggestions.

thanks,

shawn
