TEXTBOOK HOMEWORK
 
The primary text for this class is Precalculus: Enhanced with Graphing Utilities 4th Ed by Sullivan and Sullivan
 
 
Learning how to read and use the examples from a math textbook is a critical skill for any advanced math student--- for any math student.
Therefore students are assigned problems from the text.
 
Students must read the pages and put their fingers on and study the examples.
 
They must first complete ALL the "Are You Prepared Questions" AYP?
 
Then they must complete  ALL the "Concepts and Vocabulary" Questions C&V
 
Generally, they must complete the Skill Building problems SB, Pencil + 1.  This means they are to do all problems marked with a pencil, which means they have an example in the reading to help, as well as AT LEAST one additional problem from that section.  They must do all SB questions until chapter's end unless otherwise stated
 
STEP-By-STEP solutions are available at www.hotmath.com, so there are no excuses for completing the homework.
