Let V be the subspace of "vectors" in Hamilton's sense, that is, quat ernions with zero real part. Given a nonzero quaternion q, show that the mapping T V V defined by T(v) is an orthogonal mapping. This means that T(v). T(w) = u·w for all vectors u, w E V (again, V = the purely imaginary quat ernions) What is the mapping when q is an imaginary unit? Give its matrix for the basis i,j,k. For any nonzero quaternion...
