Notation: n manditory problem
Do it and write up a nice solution to be graded.
(n) helper problem
These are problems that you do not need to turn in,
but may be helpful with other problems. It may be
similar to another problem and have a solution in
the book, to it may be an easier problem of the same
general type, etc.
You might want to look these over as you come to them,
but if you are convinced that you could do the problem,
just move on to the next one. The material from
these problems will be covered in other problems.
{n} thought propblem
These problems raise interesting issues to think about
and we may discuss some of these in class as well.
You should spend some time thinking about them, but
you are not required to turn in a response. You
might like to jot down a few notes, however, in case
we discuss the issue in class. You should be prepared
to express a thoughtful opinion.
[n] ungraded problem
This might be extra practice (good review for tests)
or simply a problem that you should know how to do
but which you do not have to write up for grading.
You are responsible for the material in these problems,
and the material may or may not be covered in other
problems.
Bracketed problems do not have to be turned in.
