Homework should be turned in at the BEGINNING OF CLASS. All problem numbers refer to Tan's 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.

**Section 2.2**

Problems: 26, 29, 32, 34, 35, 40, 48

**Section 2.3**

Problems: 9-12 all, 21, 28, 52, 53, 58

*Hint:* On #53, try solving each equation for x first and then
setting them equal to each other. On #58, let x be the width and y
represent the length. Write an expression for y in terms of x.
Then find a formula for the area only in terms of x.
