Homework should be turned in at the BEGINNING OF CLASS. All problem numbers refer to the Hughes-Hallett, Gleason, McCallum, et al. book, the required text for the course. You should write up solutions neatly to all problems, making sure to SHOW ALL YOUR WORK. A nonempty subset will be graded. You are strongly encouraged to work on these problems with other classmates, although the solutions you turn in should be YOUR OWN WORK. Please list any students or faculty who you worked with on the assignment, including whether you attended the Calculus Workshop.

**Section 11.1**

Problems: 4, 5, 7, 10, 12, 14

**Hint:** Remember, the key point for this section is that you can check
whether a function is a solution for the differential equation by plugging
it into the equation.

**Section 11.2**

Problems: 2, 3, 6, 7, 8, 9

**Note:** Be sure to explain your answers carefully in the matching
questions (#6, 8 and 9).

**Section 11.3**

Problems: 1, 2, 5, 6

**Note:** Feel free to use MAPLE to generate any slope fields you
may need for the problems in this section.

**Section 11.4**

Problems: 2, 5, 12, 14, 21, 23, 27, 32
