The exam archive (which is part of the 120 Materials Website (link at right)) has old exams which are worth working for practice. I recommend focusing on the exams that I wrote. Virtually all problems on "midterm 1" exams are worth studying. For additional practice with quadratic optimization, I recommend the following problems:
Welcome to Math 120 A Spring quarter 2013.
Announcements and other useful things will be posted here during the quarter.
Textbook: The textbook for this course is Precalculus, by Collingwood, Prince and Conroy. We will use the 2012-13 edition (this is the latest edition). The book can be purchased at Professional Copy and Print, located at 4200 University Way (on the Ave one block south of the UW bookstore). It is not available at the UW bookstore.
You do not have to purchase the textbook. It is available electronically on the Math 120 Materials Website (link at right), and is linked electronically from the WebAssign homework.
Discussion Board: The course has a discussion board (link at right). This is a great way to ask questions of me in a way that will benefit all students in the course. You can ask about homework questions, studying methods, etc. You can also use it to coordinate study sessions with other students.
Homework: We will be using WebAssign for homework.
WebAssign: You can log in to WebAssign here. This will require your UW Net ID. Your UW Net ID is the part of your university email address before the @ symbol. The password to log in is your UW Net ID password.
You will need to purchase an access code before the grace period ends. You can purchase an access code on the WebAssign website after logging in.
The first homework assignment will be due on the night of Thursday, April 11.
