The vectors x1 = 1 2 (1, 1, 1,1)T and x2 = 1 6 (1, 1, 3, 5)T form an orthonormal set in
Chapter 5, Problem 7(choose chapter or problem)
The vectors x1 = 1 2 (1, 1, 1,1)T and x2 = 1 6 (1, 1, 3, 5)T form an orthonormal set in R4. Extend this set to an orthonormal basis for R4 by finding an orthonormal basis for the null space of 1 1 1 1 1 1 3 5 [Hint: First find a basis for the null space and then use the GramSchmidt process.]
