Homework

HW1: due at the start of class June 30.
LA 1.8, 2.2 parts (a) and (b) only, 2.13, 2.15, 3.2, 3.4, 3.7, 4.6, 4.10, 4.15, 4.19, 4.24, 5.10, 5.23, 6.7, 6.13.
The following Extra Problem is interesting but optional (link).

Solutions to HW 1 are up on Coursework.

HW2: due July 7.
LA 7.2, 7.4, 8.2, 8.12, 8.14, 8.15, 9.11, 10.11, 10.12, 10.21, 11.2 (note: not such a pain if you just start row elimination), 11.7, 11.14, 12.4, 12.5, 12.12

Solutions to HW 2 are up on Courseowrk.

HW3: due July 14, at the start of class
13.4, 13.6, 13.8, 13.22, 14.6, 14.10 (note: think of this as stretching first, then reflecting, although in this case the answer is the same with the operations in either order),
14.13, 15.1, 15.10, 16.4, 16.5, 16.8, 17.5, 17.14, 17.16, Extra Problem 2 as described here (link).
Extra problem 1 is optional and is about graph and network theory applications.

Solutions to HW 3 are up on Courseowrk.

HW4: due July 21, at the start of class
21.2, 21.8, 21.9, 21.12, 21.14, 23.2, 23.6, 23.10 (note the error on the Errata page!), 25.1, 25.6, 25.9, 25.15, all three Extra Problems linked here.
(The extra problem sheet says HW 5 because we are 1 homework ahead of the usual 10-week class right now. You may have noticed this pattern in previous weeks. Also, Problem 3 has a conceptual shortcut that is hard to think of; it is okay to use only this if you manage to find it. Please try to do the computations but note your final answer should be fairly simple.)

Solutions to HW 4 will be up on Coursework after 4pm Monday.

HW 5: due July 28, at the start of class
DVC 1.1(a,b,c,d,e), 1.12, 1.15, 1.18 (for the domain where it's defined!), 1.24, 2.13, 2.23, 3.16, 3.17, 4.1, 4.4, 4.9, 4.11, 4.15, 4.19, 4.20, 5.2, 5.16, 5.17, 5.18. Remember to show your work as odd problems have answers in the back!

Solutions to HW 5 are up on Coursework.

HW 6: due August 4, at the start of class
7.6, 7.10, 7.16, 7.34, 8.6 (you may use matrices instead of trees if you prefer),
8.12, 8.20, 9.6, 9.8, 9.18, 9.19, 9.23, 9.26 (you do not need to find a parametrization to do this problem!)
9.30, Extra Problem linked here. For the Extra Problem, when asked for a "direction" please provide a unit vector.

Solutions to HW 6 are up on Coursework.

HW 7: due August 11, at the start of class.
DVC 10.2, 10.6, 10.8, 10.16, 10.20, 11.2, 11.10, 11.12, 12.4, 12.6, 12.8, 12.13, 12.17, 12.18, 13.4, 13.6

13.3, 13.5, 13.8, 13.9, 13.11, 13.15, 13.17, 13.19, 13.20 (you may prefer to use geometry and linear algebra to do this), 14.2, 14.3, 14.5, 14.7, 14.13, 14.18, 14.24, 14.25
