Math 53 Homework 3 Due Wednesday 9/15/10 in section (The problems in parentheses are for extra practice and optional. Only turn in the underlined problems.) Tuesday 9/7 – Determinants, cross product Read: section 12.4. Work: 12.4: (3), (9), (13), 16 , (19), (27), 31 , 35 , (37), (43), 44 , 49 . p. 794 “The geometry of a tetrahedron”, parts 1 and 3 . (Hint: for part 1, don’t introduce coordinates; instead, express everything in terms of the vectors va = --→ SP , v b = --→ SQ , and v c = --→ SR and use vector identities.) Thursday 9/9 – Equations of lines and planes Read: section 12.5. Work: 12.5: (1), 5 , (9), (19), (25), 33 , (37), (43), 46 , (49), 56 , 61 , (63), (69), 75 . Problem 1 below. (Hint for 12.5 # 75: even though we are given symmetric equations rather than parametric ones, this is similar to examples 3 and 10 in the book.) Problem 1. In 3D computer graphics, one needs to represent 3-dimensional objects on a plane screen, by drawing a given point
