TEXT: McKeague,  Trigonometry, 6th edition, Brooks/Cole
PREREQUISITE: Intermediate Algebra with a 'C' or better, and Geometry with a 'C' or better.  Please note that in order to enroll, proof that both prerequisites are satisfied must be submitted to Cerritos College in time for this information to be recorded.  Your enrollment will be blocked if the prerequisites are not on the computer.
COURSE OBJECTIVES:  Introduction to trigonometry and its applications.  One or more of the following Student Learning Outcomes may be surveyed: 1. Understand the definitions of the six basic trigonometric Functions, and use them to evaluate expressions, solve equations, and solve applications.  2. Understand how to select an appropriate trigonometric identity to solve equations involving trigonometric functions.  3. Demonstrate understanding of and use of mathematical (trigonometric) symbols, notation and syntax appropriately.  4. Explore and analyze trigonometric functions using technology appropriately. 
GRADE:   See general course information.

You may be required to access course information, such as homework assignments, etc., on-line.  Practice test questions found in a syllabus are in PDF format.  To view them download the Adobe Acrobat Reader at
CALCULATOR:  A TI-84Plus or other suitable graphing calculator is required. 
Tue. July 24, 2012*, is the last day to withdraw from the class and receive a W
I cannot assign a W grade after the deadline.*. 
If you cease to attend, withdraw through Admissions and Records, to avoid getting an F.
HELP:  See me in my office, PST 205.  It is a good idea to form study groups outside of class. 
Enroll in Supervised Mathematics Tutoring. 
Go to the Academic Support Center, in the lower level of the east side of the Learning Resource Center (library building). 
Ask questions during the lecture.  Before each lecture you can ask questions about textbook problems and examples.
HOMEWORK (HW) & GROUPWORK (GW): Plan to spend eight or more hours per week outside of class reading, doing assignments and attending tutorial classes.  Unless otherwise stated, the default selection for practice HW is every tenth problem starting with #1,  from the exercises at the end of each section in a chapter.  These should be completed by the due dates below, and will have to be turned in.  Work must be shown to get credit.  For HW and GW ten percent of the value of the work will be deducted for each class late.  No late work will be accepted more than 4 classes late or after AUG. 29, 2009.  Students must read the textbook, including examples, and work additional problems as needed.
The schedule below is only approximate.    DATES, TOPICS AND TESTS ARE SUBJECT TO CHANGE.  (*Dates determined by admissions office - you must confirm these with that office.)  Topics & dates below are very rough.  They will gradually be revised.
