vector AB. Then compute and redraw AB as a vector in standard position. (a) A = ( 1, - 1 ), B = (4, 2) (b) A = (O, - 2), B = ( 2, - 1 ) (c) A = (2, f), B = (t, 3 ) (d) A = (t, t), B = (i, t) 6. A hiker walks 4 km north and then 5 km northeast. Draw displacement vectors representing the hiker's trip and draw a vector that represents the hiker's net displacement from the starting point. Exercises 7- 1 0 refer to the vectors in Exercise 1.
