Readings: Section 10.3, 10.4
Due to the holiday, only Section 10.3 is due on 9/8.
HW3 Part II due on M 9/13
: Sec. 10.4, Prob. 16, 26, 30, 34 (see the definition of coplanar on page 542 right above Example 5), 36 (optional) (graded P. 16,26,30,34)
 HW4 due M 9/20 (Readings: Section 10.5, 10.6).
 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.
