Unformatted text preview: If A and B are the points A = (1 ,1) , B = (4 , 2) draw the vector AB then compute and redraw AB as a vector in standard position. Solution: AB = OB OA, where O = (0 , 0) is the origin. Sketch! (continued . . . ) 4 AB = OB OA = [4 , 2][1 ,1] = [41 , 2(1)] = [3 , 3] . (Sketch of AB = OC for C = (3 , 3) . ) 5. linear combinations, standard cordinates 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....
