Math problem trigonometry
Sep 15, 2010, 04:43 pm
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

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