Introduction to Mathematical Economics


The course will develop the mathematical tools of calculus and matrix algebra and show how these tools may be used in doing economic analysis.  Topics that will be covered include continuity, derivatives and optimization of functions of one variable; matrices, determinants and inverse matrices; partial derivatives, unconstrained and constrained optimization of functions of several variables; comparative statics.  If time permits, there may be an introduction to economic dynamics.

Using Maple:

Using the "Maple" software package is not required for this course. However, it is a powerful and useful package, especially if a student plans on going on to Graduate Studies. Students are encouraged to try it out.
