**Homework 1 is due Monday 20 September** at the start of class, except that question #1 consists of the work from *WeBWorK *set **421HW1** and that *WeBWorK *part is due **Sunday 19 September 5:00 p.m.**

See the Homework page for a link to the Homework 1 assignment, in the form of an Adobe pdf file.

**Note: ** *WeBWorK *Problem 5 does not recognize the “sqrt” function notation. It seems to require that you enter your answers using (…)^(1/2) notation for square-roots of (positive) real numbers. Or, instead, you can use decimals rather than exact expressions involving square-roots at all.
