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 1.3**

Problems: 2, 4, 7, 9, 15, 16, 17, 20, 25, 26, 28*, 31, 32

**Extra Credit:** Problem #28 is extra credit. Your graph must be
very detailed to recieve any credit.

**Section 1.4**

Problems: 1, 2, 9, 13, 19, 22, 23, 26, 27, 29, 32, 38, 45

**Important:** When the problem asks for a numerical answer
(eg. problems 2, 9, 13, etc.) or requires a constant in a formula,
give the **exact** answer first (in terms of logs and without decimals)
then use your calculator to obtain a decimal approximation.
For problem #38, the term half-life means the amount of **time** it takes
for a substance to lose half its original value.
