Math 116,

Solutions to Assignment 4 have been posted to the website, in the "Assignments" section. Please look them over, and if you spot any errors, or have any questions, contact me or post your observations in the "Discussions" section.

Note: Your answers were a bit more, um, "diverse" than on Assignment 2, so I think everyone could benefit from looking at the solutions on the website.
