Facets:
value: in two and three dimensions
type: OTHER
Source sentences:
text: In two and three dimensions all rotations are simple, in that they have only one plane of rotation.
text: The rotation is specified by giving the two planes and two non-zero angles, α and β (if either angle is zero the rotation is simple).
text: The conjugate of that eigenvalue is also unity, yielding a pair of eigenvectors which define a fixed plane, and so the rotation is simple.
