Homework #2
A:
Don't forget! For full credit you must check your
Ch 1.1: Examples 1-4; Problems: 7 - 11, 15 – 17, 20 - work check your work on all 1.1 problems!
26, 29 – 31, 37 - 38, 42, 44, 49, 52-53, 61-71, 76-80,
89
Note: The problems presented in class were not
from the textbook. I am assigning the textbook
Ch 1.2: Examples 1-2; Problems: 5-7, 10 -12
examples as part of your Homework part A (i.e.
completion) – What we did in class should have
given you the tools you need to understand the
B: Homework 2B
textbook examples - I would recommend that you
work the examples first, trying to solve them
without looking at the solution. Once you've
solved them – compare the solutions.
Example 4 gives a solution technique we did not
discuss in class.

For example:
If your function is given by:
