Welcome to the homepage for ECON384, Math for Economists. Below you will find links to all class lectures, as well as some relevant links I have or pulled together from the internet. If you have anything you think would be worth adding, please let me know. You can find me in my office on: Tuesday and Thursday during two time slots, 10:45am-12:00pm and 2:00pm-3:15pm. Office hours are occasionally rescheduled due to conflicts. Please try to make an appointment before coming by.

Note on textbook: This semester we are using Pemberton & Rau’s “Mathematics for Economists.” You can get a discount for this book, by first registering for the CORE Team Econ textbook which we will also use. The CORE book is free, but you have to register to get the deal. After registering, you can get the discounted copy of P&R at for \$35. Links to relevant sections are provided throughout. While it might be confusing, I am doing this in an effort to minimize costs to you. The CORE book will be used to reintroduce you to the intro concepts that are a prerequisite for this course (and often forgotten).

### Mathematica

Mathematica is software that is used for a wide variety of mathematical and economic purposes including running simulations, solving linear algebra problems, performing regression analysis, building models, to name only a few. Mathematica is incredibly powerful, and will help you to check through taking derivations, solving integrals, examining non-linear problems, and graphically displaying your work. We will only begin to touch on what Mathematica can do.
