• Sec. 10.5, Prob. 14 (hint: part (b), xy plane is given by equation z=0, yz plane by x=0, etc), 24 (two planes are parallel iff their normal vectors are parallel), 27 (Three points on a plane that are not aligned determine two vectors and the cross product of these two vectors determine a normal vector), 30 (optional), 50, 54 (optional);
• Part II due M 9/27. Sec. 10.6, Prob. 12, 16, 26 (completing the squares), 28, 32.
