Question

Find u * v and show that it is orthogonal to both u and v?
u= <-3, 2, 3>

v= <0,1,0>

please help me!

Answer 1

Apply dot product!

Answer 2

First using cross product
u x v = -3i + 3k
Then dot product of: u . ( u x v)
v . ( u x v )
Since both result are 0, this proves ( u x v) is orthogonal to both u and v.
