Sorry for the math on a Saturday night--

I'm sitting in lab and I'm having trouble thinking through this since it's been at least 7 years, maybe someone else is more alert than me?



If I've got something moving 5 degrees about the X axis in one frame.

Another frame of reference reads that as say, 4.2 degrees about the X axis and 2.5 degrees about the Y axis.

How would I go about figuring out the rotation between one frame of reference and the other?

If that problem is really complex (matrix inversion or something) is there a way I could take a guess and see if that makes sense?
