Use vector analysis wherever possible.

1. 1st Ed: p13, q31a-f,h-j, 2nd Ed: p17, q31a-i. if they can be vectors, count them as such.
2. 1st Ed: p13, q32, 2nd Ed: p17, q32. Do it both graphically and analytically.
3. 1st Ed: p14, q48, 2nd Ed: p19, q46. Use vector calculus only, no trig.
4. 1st Ed: p32, q66, 2nd Ed: p38, q66.
5. 1st Ed: p32, q82, 2nd Ed: p40, q82a, where B should be corrected to $(1,-3,4)$. Do it without finding the actual sides of the parallelogram. Vector calculus only, no trig.
