suppose that v,w,z are vector in R^n such that v is orthogonal to z and z is
orthogonal to w. Then
(a)For any orthogonal n*n matrix H,we have that Hz is orthogonal to both v & w
(b)v+w is orthogonal to z
(c)v is orthogonal to w
(d)For any orthogonal n*n matrix H, we have that Hv is orthogonal to z
我知道b是對的
c是錯的
a d不太會選
