# 4031 Spring 2018

Here is the syllabus, and links to
the
free e-book and
errata.

The grader for the course is Vishwa Dewage.

## Checking your grade

I am not using Moodle. I have my own program, Noodle, which lets you
check that I've recorded your grades correctly. To
log in to Noodle, you need a login name, which is your myLSU username,
and a password, which is initially your student ID. You will be
required to change it the first time you log in.

## Graded homework assignments

Note: the individual problems are numbered because your grades for
each problem are recorded individually in Noodle. Mostly these are
exercises in the text; For example, 1.3 refers to the problem in the
exercises for section 1.1 on page 7.

Each assignment must be handed in on the due date in class. No
late assignments will be accepted.

- Due 1/19.
**Postponed until 1/22.**

**1:** 1.3. Since the additive cancellation law (a + c = b+c
implies a = b) was proved in class, you may use it if it helps.

**2:** Use the result of 1.3 and the Axiom of Trichotomy to
prove that the real number 1 is positive (that is, 1 > 0).

## Test solutions.

Originally, I intended to post answers to the short questions only. As
of test 2, I decided to include proofs as well. These are examples of
correct proofs, but not the only, or necessarily the best. The
solutions for test1 have been updated accordingly
