I'm confused on number 6. How would I do the cross product with something like that? Do I need to rewrite it in component form? If so, how do I do that?

Sorry for the cut off text. It says "Verify that the cross product is orthogonal to a and b"

I was thinking that maybe I do have to change it into component form using the unit vectors but I don’t know how I’d do it with the sin and cosine
