From the results of the first test, its clear that I deserve some blame for not being clear enough about linear transformations and not giving people enough time to digest them. Thus I'm giving the option of having the final exam worth more in place of the first test. Details are on the sheet with assignment 5.
Assignment 5 due Thursday June 10. Solutions.
Test 2 will cover sections 2.1, 2.2, 2.3, 2.4 up to but not including "Inverses of Partitioned matrices", 2.8, 2.9, 3.1, 3.2, and the part of 3.3 called "Determinants as area or volume".
Assignment 6 due Thursday June 17. Solutions.
Solutions for the second test.
Assignment 7 due Tuesday June 22. Solutions.
