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

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.
