The radius of this circle is 1. With sinus and cosinus is it possible to get every coordinate of this or another circle. I tried to do so in my scene. In the Center of the circle is a red big sphere and a smaller blue sphere should do its circles around it (render scene to see what i mean!). My problem is that the calculated coordinates (see pic 1) are not the same as those i calculated myself (see pic 2). I need this procedure so please try the scene out and write me what went wrong as a mail (psi_control@hotmail.com) with a solution perhaps.

Pic1:
type in calculator 90 then sin the correct number is one as shown in pic2. do the same for cosinus.
Pic2:

I have added the scene files in a zip.
Thanks for help in advance.
