Name
Instructions.
Your work on this exam will be graded according to two criteria:
mathe
matical correctness
and
clarity of presentation
. In other words, you must know what
you are doing (mathematically) and you must also express yourself clearly. In particular,
write answers to questions using
correct notation
and using
complete sentences
where
appropriate. Also, you must supply su¢ cient detail in your solutions (relevant calculations,
written explanations of why you are doing these calculations, etc.). It is not su¢ cient to just
of thumb, the harder that I have to work to interpret what you are trying to say, the less
credit you will get. You may use your calculator but you may not use any books or notes.
