Unformatted text preview: when u = [1 , 2 , 3] . Solution: For v we have  v  = v v, so for v = [ v 1 , v 2 , v 3 ] ,  v  = p v 2 1 + v 2 1 + v 2 1 . so  u  = u u = 1 + 4 + 9 = 14 . Then the unit vector in the direction of u is 1 14 [1 , 2 , 3] = [ 1 14 , 2 14 , 3 14 ] . continued from week 1: 5. linear combinations, standard coordinates and new coordinates. We also covered 1.1  #11, 20, pg. 14 6. dot product, right angles and orthogonal vectors. We also started Section 1.2 and covered 1.2  #1....
