Homework should be turned in at the BEGINNING OF CLASS. All problem numbers refer to the 4th edition 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.

**Note: Please list any students or faculty who you worked with
on the assignment. **

**Section 1.3 (pp. 21 - 23)**

Problems: 2, 4, 10, 11, 18, 22, 26, 27, 30, 36, 38, 44

**Section 1.4 (pp. 27 - 28)**

Problems: 6, 10, 14, 20, 26, 28, 32, 40, 46

**Note:** When the problem asks for a numerical answer
(eg. problems #10 and #14) or requires a constant in a formula,
give the **exact** answer first (in terms of logs and without decimals)
then use a calculator to obtain a decimal approximation.
For problem #46, recall that half-life is the amount of **time** it takes
for a substance to lose half its original value.

**Section 1.5 (pp. 35 - 36)**

Problems: 6, 16, 22, 23, 26, 30, 38, 46

**Note:** For problem #6, draw the angle and find the
**exact** values of sine, cosine and tangent. (Ignore the book's directions.)
