Homework should be turned in at the BEGINNING OF CLASS.
All problem numbers refer to *Single Variable Calculus, Concepts and Contexts* 3rd ed.,
by Stewart, 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. Please staple your assignment.

** Important: ** At the top of your homework, please list the names of any students or faculty who you worked with
on the assignment.

**Section 7.4, pp. 532 - 534**

Problems: 18a, 19, 20

**Hint:** For problem #20, part b), the "equivalent annual
interest rate" is the rate **r** such that if you compound the
initial amount annually for t years at the rate **r**, you would get the **same**
amount as if you compounded continuously for t years at 6%. Your job
is to find **r**.
