Benefits of MyMathlab for Students At the University of Alabama:

Student Testimonials “Using MyMathLab to do homework was quite easy. Doing my homework online gave much practice for the test given in class. What I truly like about MML is that it tells how to work out each problem and what formulas to use. By using MML I found myself better prepared for the multiple choice final exam.”

Student Testimonials “I like that MyMathLab lays out all of the things that you need to study. It keeps things in order, keeps you on track, and helps you learn how to solve all of the problems needed to pass the course. I never would have thought that I could have this much help in math while taking it online, but I really think that MyMathLab is a great resource and everyone should use it.”

Student Testimonials “I was able to work at my own pace. I didn’t feel like I was pressured to keep up with anyone, and I didn’t feel like I was being held back by anyone.”

Textbook A custom edition taken from Precalculus: Graphs & Models, Fourth Edition by Marvin L. Bittinger, Judith A. Beecher, David J. Ellenbogen and Judith A. Penna (2008). You must purchase the book in order to acquire the student access code to MyMathlab, or buy it online with a credit card.

Don’t Drop Without Dropping By The last drop day for the course is October 29th. If you get to the point where you are considering dropping the course, please speak with me, the department chair (Dr. Carter) or the assistant to the chair (Dr. Brick) before dropping.

Homework Buy your book (binder or e-book) if you haven’t already. If you haven’t registered to MyMathlab, make sure you bring your student access code to lab on Friday. Read Section R.1 The Real Number Line

1-Minute Group Question In small groups of 2 or more, introduce yourselves and ask each other any questions you have about the course. (If no ones knows, you’ll have a chance to ask the instructor.)

Motivation…

The University Experience

Now time for the Pre-test

Next time… Why learn Precalculus Algebra? The real number line.

Why study precalculus? (Why learn algebra?) Precalculus = Algebra. Needed preparation for precalculus and very useful in its own right. Algebra: Understanding and describing relationships between quantities, especially in ways that help you find solutions to problems.

Relationships between quantities: # of eggs and # of cartons Cost of tuition and # of semesters attended. Monthly gas bill and average temperature over the month.

# of eggs and # of cartons In words: However many cartons you have, you have twelve times that many eggs. Algebra:(algebraic equation) Let the number of cartons be represented by the letter C. Let the number of eggs be represented by the letter E. Then we have: E = 12  C.

# of eggs and # of cartons Algebra:(graph)

Algebra: Understanding and describing relationships between quantities, especially in ways that help you find solutions to problems. Suppose you have 20 feet of fencing. What is the largest area you can enclose? If one side has length L, the other side must be 10-L. The area will be L  (10-L).

Optimal Length of One Side
