Hi, Dave,
This maybe an old question. I wish to calculate the coordinate of  (a,b) in pixels under the screen resolution of (1960,1200). The angle between is 10 degree.
Is there a formula I could refer to? I used something like this but does work.

/ circle_a=1px*(expressions.circle_x+300*cos(0.174533))
/ circle_b=1px*(expressions.circle_y+300*sin(0.174533))

Thank you ;)
