Hi

Does anyone know how to take the invers function of sin,cos and tan??
I would like to calculate the function sin^-1 and so on..

I am trying to make a "robot arm" with servos, so I need to find angles for the servos.

Thanks in advance
Mads

Just a hint:
Do not use ATAN(); use ATAN2() - after you have understood what it does, of course :-)
