Hey guys!

I just had some questions relating to orthogonality!

10) Show that the given vectors form an orthogonal basis for R^2 or R^3.

(Work is attached to file)

12) Determine whether the given orthogonal set of vectors is orthonormal. If it is not, normalize the vectors to form an orthonormal set.

(Need help on this one)

[1/2] , [1/2]

[1/2] [-1/2]
