MATH 415 P13/Q13 SPRING 2012

HW is collected on Thursdays at the beginning of class.
HW can also be dropped in the box outside my office before Friday 11:30 am.

Week 1 January 17, 19
Tu in class we did problems (1.1) 27, 37 and (1.2) 29. 61 HW1 : (1.1) 2, 4, 7, 29 due Th 19
Th we did matrices in RREF and elementary row operations (resp. top and bottom of page 16) and two ways to evaluate a product Ax (top page 29 and bottom page 30) HW2 : (1.1) 18, 23 (1.2) 2, 4, 18, 22 (1.3) 14, 36, 58 due Th 26
Week 2Janunary 24, 26
Tu we did problems (1.1) 17 (1.2) 46 (1.3) 37 and defined linear transformations (Defn 2.1.1 and Thm 2.1.3)
Th we pointed out the connection between composition of linear transformations and matrix products (L after T has matrix BA - Defn 2.3.1 / Thm 2.3.4) and we used row reduction techniques from Chapter 1 to find the inverse of a matrix (pages 81 and 82)HW3 : (2.1) 6, 8, 44, 52 (2.3) 4, 20 (2.4) 12, 18 due Th 2
Week 3 February 31, 2
Tu we showed that projections on a line or a plane are linear transformations, we found a short formula for projection on a line (x goes to kw where k = (x.w)/(w.w)), and we derived in three different ways the matrix A for a projection (for this part use notes from class - I will upload my own notes next week - rather than section (2.2) from the book). This completes Chapter 2
Th we went through sections (3.1), (3.2), including important definitions: the image im(T) and kernel ker(T), linear combinations and span, linearly independent / linearly dependent and basis, and the Theorems 3.1.3, 3.1.4, 3.1.6, 3.2.2HW4 : (3.1) 10, 16, 30, 34, 42, 50, 52 (3.2) 2, 6, 8, 18, 32 due Th 9
Week 4 February 7, 9
--- we will do Sections (3.3), (3.4)
--- we will do Sections (4.1), (4.2)
