Talk:Vector rotation

Quaternions

Any help creating a quaternion methods section for the article would be greatly appreciated. Also, I wonder if the final equation shown is sufficient for this article, or whether I should expand the final answer to show the full calculation of r_xx, r_xy and the final values of rotated vector in terms of V1 and V2.
