Homework should be turned in at the BEGINNING OF CLASS. All problem numbers refer to Bilodeau and Thie's book, the required text for the course. You should write up solutions neatly to all problems, paying particular attention to your arguments and proofs. 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 3.2**

Problems: 2a, 6

**Hint:** For problem #2a, start by reading the proof of the first part
of Thm. 3.2.3 (the BLT for functions). Amend the proof in the text to
the subtraction case.

**Section 3.3**

Problems: 1b, 1c, 1f, 3 (parts a, b, c, g, h), 5a, 5c, 5e, 6

**Hint:** The only problems requiring rigorous proofs are #5 and #6.
For problem #5, the proofs are similar to those you have been doing
in Section 3.1. Use class notes and the text for specific examples.
For problem #6, prove any claims you make using the appropriate
definitions of the section. Otherwise, explain why no claim can
be made.

**Extra Problem:**
Prove the Squeeze Theorem for functions. See class notes from 2/13 for
precise description of the theorem and for hints.
