Homework Statement
Find a unit vector that is orthogonal to both i + j and i + k.
I know I can solve this using the cross product of the two. But This chapter is about
dot product and not cross product.
I am not sure how I could go about solving this problem using the properties of a dot product.
This is just a review, in test I would use the cross product.
