What are eigen values?
Because the original vector is not pointing in the same direction as the final vector (it is at an angle of 60 degrees to it).
Mmm, no, the axis around which I rotated the coin didn't change at all, by definition.

You are doing a rotation in 3 dimensions. Surely the original example meant two dimensions. In 3 dimensions, the axis of rotation is indeed an eigenvector.
