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.

**At the top of your assignment, please list any students or faculty who you worked with
on the assignment.** If you received help at the Calculus
Workshop please include "Calculus Workshop" in your list as well.

**Section 2.5**

Problems: 3, 10, 11

**Section 2.6**

**Section 2.7**

Problems: 1, 2, 3, 6, 8, 9

**Note:** For problems #6, 8 and 9, you may want to use
a graphing calculator or MAPLE to determine whether the function
is differentiable at x = 0. EXTRA CREDIT will be given in problems
8 and 9 if you correctly use the limit definition of the derivative
to answer the question.
