Quaternions EXERCISE 8.36. Verify (36), (37), and (38). (35) We then have (36) v*v = ||v||² = a² + b² + c²+d². We must be careful about the order of multiplication. One checks that (37) (a1 + bi + cj + dk)* = a1 − bi − cj – dk. (vw)* = w*v*. Suppose that v0. Then v has a parallel with C is striking. Furthermore we even have ||vw||² = ||v||²||w|| ². (38) iplicative erse, namely. The
