**Welcome** to Mathematical Foundations for Finance! This
course is an introduction and review of some mathematical tools that will
be essential for your later coursework and your career. Ideally, you want
to learn these tools well enough to have them at your fingertips, so you
do not have to spend time looking them up when you need them.

**Practice Exam** Here is a practice exam. It is too long
to be a real exam because I wanted to cover a variety of types of problems
you might see on the actual exam. In the actual exam, I will also include
a few relevant relatively complex formulas (the Kuhn-Tucker conditions and
the basic formulas for eigenvalues and eigenvectors), but mostly you are
supposed to remember the formulas you need.

**Practice Problems!** Here are some problems and answers
from another
class previously offered by Yajun Wang. The link on this pages tells which
problems test topics covered in our class (but the other questions and answers
are there in case you are curious). For this class, ignore the
suggestion to check the results using Matlab.

I recommend that you print a set of slides before class for taking notes. I have developed some of the slides (in pdf), and there are also many slides (in PowerPoint) developed by Yajun Wang, a brilliant PhD student who graduated this year and is now on the faculty at the University of Maryland.
