This problem about vectors is giving me some trouble. Help would be greatly appreciated.
Let v= <2,3,2> and w= <4,6,5>
a) Find a unit vector that is orthogonal to both v and w.
b) Find the angle formed by vectors v x w and w x v
c) If u= <-1,4,8> find the cosine of the angle formed by vectors u and v x w
Thanks so much!!
