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### [at] hotmailcom) with a solution perhaps.

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

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

sin(radians(A))                cos(radians(A))

The title says it all. This is a common mistake. I made it a couple
dozen times.
