Once I found the X, Y tilt angels from an accelerometer . How do I use that to find the final angel?

angle = tangent(y/x)

Ermm, I think that should be y/x=tangent(angle), or
angle=inverse tangent (y/x), or
angle=arctan(y/x)

Arctangent is another name for inverse tangent.

You are right, Ron. I have not used tangents in a long time!

Haha! That what I thought, but I havn't done math for sooo long.... kinda forget stuff if you don't do it. Thanks!
