**Last offered in Spring 2012. Replaced by MAT175, beginning Fall 2012.**

This course covers selected topics from Linear Algebra and Vector Calculus to provide a *minimal* mathematical foundation for more advanced quantitative work in the Economics department. Although economic examples will be used freely, **this is a math course, not an economics course**. Examples from other disciplines may also be discussed. The first half of the course is a **quick overview of basic linear algebra **topics, all of which are covered with more depth in 202. The second half of the course develops techniques for **optimization of functions of several variables**, many of which are also taught in 201. For the most part we will look at functions of 2 or 3 variables, but the techniques readily extend to higher dimensions, and students should have an open mind, ready to work with more than three variables on occasion. Emphasis on concrete calculations and intuitive reasoning rather than formal proofs.
