Read sections 1.1 through 1.3 in our textbook, and solve the following problems:
- Problems 3a and 3bcd on page 6, problems 1, 7, 18, 19 and 21 on pages 14-16 and problems 8, 9, 11 and 19 on pages 20-21. You need to submit only the underlined problems.
- Note that the numbers
,
,
,
,
and
are all divisible by
. The following four part exercise explains that this is not a coincidence. But first, let
be some odd prime number and let
be the field with p elements as defined in class.
- Prove that the product
is a non-zero element of
.
- Let
be a non-zero element of
. Prove that the sets
and
are the same (though their elements may be listed here in a different order).
- With
and
as in the previous two parts, show that
in
, and therefore
in
.
- How does this explain the fact that
is divisible by
?
You don't need to submit this exercise at all, but you will learn a lot by doing it!
