The matrix

R

$$ describes a rotation by some angle

$\backslash$omega

$$ around some axis. Assume $$

$\backslash$omega

$!=$

$0$

$.$ Write a Python function axis$($alpha$,$ beta, gamma$)$ that computes one of the two unit vectors

$\backslash$pm

a

along the axis of the rotation. Think numerically and do not use weird formulas you need to look up$.$

Show your code and print the unit axis for the following four combinations of angles:
