Math for Game Developers - Quaternions and Vectors

We learn how to rotate a vector using a quaternion. During the video I said that I'd link a book where you can find the derivation of the vector rotation equation. I thought it would be in "3D Math Primer For Graphics And Game Development" by Fletcher Dunn and Ian Parberry but I can't actually find it in there. Still a good book though.
