Linear Algebra, Spring 2017

Information About the 2nd Midterm Exam

Our second exam will be on Friday, 3/31/2017. It will
cover the material presented in class and in assignments since the
first exam. That includes sections 4.1 -
4.3, 4.5 - 4.6, and 5.1 - 5.2 of the
text, as well as the determinants
handout
and the difference equation
models handout. Please
remember to bring your
portfolio to the exam for my review. Be sure that a copy of your
group's first exam solutions is included.

At the bottom of this page is a link to some sample exam
questions. It is intended to give you a feel for the *kinds*
of
questions that will be asked on the real exam, and for the format of
the
real exam. However, this sample problem set is not intended
to reflect the length of the actual exam. The actual exam will be
shorter than the sample problem set.

Please
Note: This is not a comprehensive review of all
the material
you
will be responsible for on the exam. Neither the sample problem set,
nor the
real exam, makes any attempt to include __everything__ the class
has covered. There is just too much material to test
on
one in-class exam. Some things we have studied will not appear on the
exam
at all. Both the real exam and the sample problem set contain questions
concerning
a *subset* of all that we have covered. You should expect
some material that was not on
the
sample problem set to show up on the real exam, and also that some
material
covered on the sample set will not
appear on the real exam. To be sure you are ready
for
the exam, you need to know all the material we covered -- not just the
subset
that appears on the sample exam.

I recommend that you review all the material *first*.
You should
study definitions
and terminology (the language of the course), procedures (how to *do*
things), and theorems (factual knowledge about what is true). Be
prepared
not only to do procedures (such as finding determinants and
determining whether a given set of vectors is a basis), but also to
explain how and why you do the
steps
you do, and why those steps are valid. To do this, you need to
know correct
statements of theorems, what those statements mean, and have some
understanding
of *why* the statements are true.

After studying all this material in the text, try to complete the items on the sample problem set under something like real test taking conditions: no notes, book, or other references. Afterward, review the course material again to find answers to any problems in the sample set that stumped you. Any unresolved questions from the sample problem set can be discussed in class on Tuesday, 3/28.
