10.1: 3-4, 24.

12.5: 4, 10, 12 (only the parametric equation for these; don't worry about "vector equations" or "symmetric equations"), 24, 28, 32, 45-46, 74, 78, 79. Do not use the distance formulas from the book for any of these! You should be thinking about the geometry, like we did in class.

13.1: 2, 6, 18, 27 (don't sketch), 49-50 (find intersection points, ignore "collision").
