Anyone familure with it?
I would like to use it for finding the general solution of equations.
cos(x)-1=-cos(x)
On the calc I get x=(6*@n154+1)Pi or x= (6*@n154-1)Pi
3 3
I know that the 154 part increses everytime I do another problem like this.

Kenny Felder might know, he knows lots about the 83 and 84, and so might be able to help you.
Visit http://www.ncsu.edu/felder-public/kenny/papers/ti.html, and his email address is at the bottom.
