A collection
of assorted

SUPPLEMENTAL
SOLUTIONS

to problems
found on past MT1's;
some familiar, some not.

Supplemental review material
is organized in no particular order;
it makes no particular matches
between solutions and. problems.
It is for you to sort through
as desired, as is.

The material found in the
leftmost box of this row is purely supplemental;
it should not be used before nor instead of
any of the review materials
mentioned above this box.
This packet is provided primarily for people who feel they have exhausted
all the details contained
within the exams S17, SU16, SU15,
as well as HW and Practice problems.
