Note: Homework Hints are given only for the Level 1 and Level 2 problems.
However, as you go through the book be sure you look at all the examples in the text. If you need hints for the Level 3 problems, check some sources for help on the internet (see the LINKS for that particular section. As a last resort, you can call the author at (707) 829-0606.
On the other hand, the problems designated “Problem Solving” generally require techniques that do not have textbook examples.
There are many sources for homework help on the internet.

There are many problems throughout the text labeled IN YOUR OWN WORDS. Just relax; do not be afraid to give your opinion. For the most part, these questions do not have “right” or “wrong” answers. You should spend about five minutes in answering each of these questions.
Don’t be afraid to guess at these examples; see Example 1.
Trace out the figure in the book on your paper and then draw a secant line (using a straightedge). Now, let the second point on the curve approach (along the curve) the given point and rotate your straightedge along different secant lines until you reach what you think is the tangent line. Use your straightedge to draw this line (if possible). See the tangent problem in the text.
Evaluate the given expression for n = 1, 2, 3, 4, …. Look for a pattern in the values of the result. See Example 1.
Estimate the number of square units by counting squares. See the area problem.
