[EquisMetaStock Group] How to determine the x & y coordinates based on angles for circle?

[chichungchoi <no_reply@xxxxxxxxxxxxxxx>]

Does anyone have any suggestion on how to determine the x & y 
coordinates based on angles for circle? 
For example, the radius of circle is 1,
if the angle is 0 degree, the the coordinate is (1,0),
if the angle is 90 degree, the the coordinate is (0,1),
if the angle is 60 degree, does anyone have any suggestion on how to 
determine the coordinate?
Thank for any suggestions
Eric
