What's here: Lecture handouts and homework exercises are in Adobe Acrobat PDF format. Most computers come with Acrobat Reader already installed, but you can also download a free copy of Acrobat Reader for virtually any kind of computer (Mac, Windows, Linux, etc.) from the Adobe web site (www.adobe.com/prodindex/acrobat/readstep.html). If you have computer problems, please use the computers in Cowles Library. Computer problems are NOT an acceptable excuse for late homework.
