Question
(a) Suppose u and v are known nonzero 3D vectors which are orthogonal to one another.
Explain whether it is possible to find a unique 3D vector x satisfying x x u = v and
x•u = ||u||. You do not need to explicitly write the components of x but should describe
in detail how to obtain x from u and v.
(b) In the specific case that u =
(2, 2, 1) and v = (1, –1,0), find x as in part (a).
