Well I haven't done trig since high school so it took a while to relearn off google images search.
Anyways Stephen's code was more pseudo and not copy paste. And I learned there's an atan! Which I only tried to solve the rig with tan. I'll post my rig up once I clean it up a bit. Now all I need to do is remake my rig in after effects and maya, I'm not getting these maya expressions at all.
