Graphing Calculator: We will use these to aid us in our study of trigonometric functions and their applications. I strongly recommend the TI-83 or better. TI-83 s are available for rent from the SCC bookstore for around $25 a quarter. Other calculators are allowed but I may not be able to provide assistance on them. If you are unsure whether your calculator is appropriate, please ask me. Graphing Tools: A transparent ruler with metric scale. PREREQUISITE: Math&141 with a grade of 2.0 or better, or a score of 70 or higher on the College Algebra COMPAS test, or instructor s permission. Students taking Math& 142 should already have studied exponential and logarithmic functions. Please see me if you are unsure whether you are qualified to take this class. COURSE DESCRIPTION: Math& 142 is a second course in the study of functions and will focus on the trigonometric functions and their applications. In particular, we will study right triangle trigonometry, trigonometry on the unit circle, trigonometric and inverse trigonometric functions and their transformations, the Law of Sines and the Law of Cosines, trigonometric identities, solving trigonometric equations, vectors, polar coordinates, parametric equations, and applications. We will develop skills in problem solving, reading and writing mathematics, and using technology effectively. This course is intended for engineering and science majors who plan on taking the calculus series Math&151, 152, 163, and 264. At one time or another this quarter, we will be discussing topics in the following sections... Chapter 5 Trigonometric Functions: Unit Circle Approach ( ) Chapter 6 Trigonometric Functions: Right Triangle Approach ( ) Chapter 7 Analytic Trigonometry ( ) Chapter 8 Polar Coordinates and Parametric Equations (8.1, 8.2 and 8.4) Chapter 9 Vectors in Two and Three Dimensions (9.1 and 9.2) To see how this course fits in with other math courses at SCC, check out the math department s curriculum flowchart at MATH EXPECTATIONS PRECALCULUS I SKILLS: It is assumed that you are competent with the material presented in Chapters 1 4 of our text. If not, then review the material as needed. If you find it difficult to complete this review with confidence,

2 and you haven t taken Math&141 here at SCC (recently), you might consider changing your class schedule. This following is a list of skills that you should have mastered BEFORE taking Math& Graph polynomial, rational, radical, exponential, and logarithmic functions and their transformations. 2. Perform operations on functions, find compositions and inverses of functions. 3. Solve polynomial, rational, radical, absolute value, exponential and logarithmic equations. 4. Do applications involving polynomials, exponentials and logarithms. 5. Model and curve fit using linear, quadratic, rational, exponential and logarithmic functions. PRECALCULUS II SKILLS: These are the skills you will develop throughout this course. 1. Use circular and inverse circular functions. 2. Evaluate trigonometric functions of the basic angles (in radians) and their multiples. 3. Graph transformations of trigonometric functions. 4. Do applications involving right triangle trigonometry, including the Law of Sines and the Law of Cosines. 5. Use trigonometric identities to solve trigonometric equations. 6. Convert points and equations from polar to rectangular form and vice versa. 7. Perform basic vector operations geometrically and numerically. 8. Do applications of trigonometry including vectors. 9. Sketch polar curves. 10. Sketch curves defined parametrically. WHAT DO YOU HAVE TO DO? ATTENDANCE: One of the best things you can do to help yourself succeed in this class is to attend class and participate EVERY SINGLE DAY!! If you miss a class, it is your responsibility to study the material, prepare to learn the next lesson and determine any announcements that you may have missed. Class Expectations: I expect you to be responsible. This means Come to class prepared everyday. Bring a pencil and paper to take notes with. Participate in the lectures answer my questions, ask your own questions, work on problems that I give you, etc... Turn off your cell phones and any other electronic gadgets during class time. Come see me during my office hours if you have questions. If for some reason you cannot make it to class, find out what information you missed in your absence by talking to your classmates or to me. HOMEWORK: To succeed in this class you must practice at home what we do in class. This means, DO YOUR HOMEWORK!! Homework problems will be assigned from the text on a weekly basis and will be collected most Tuesdays at the beginning of class. NO late homework will be accepted. All homework will be posted on the Homework page of my website ( You will earn a total of 10 points for each homework assignment: up to 4 points for completeness of the entire homework assignment and up to 6 points for correctness (three problems will be selected and graded, 2 pts each). I will drop your lowest homework grade at the end of the quarter. In addition to the textbook problems, worksheets may be assigned and collected as part of your homework grade. Please note that some students may find it helpful or even necessary to do more problems from the book than I assign. You must be honest with yourself to determine whether you sufficiently understand the material, and if you don t, read and practice more. Guidelines for handing in your homework: Please adhere to the following policies when handing in your homework. I may deduct points on homework sets that do not adhere to them... Use 8.5 x 11 paper that has no tears or fringe. Put your name on everything and staple all pages together.

3 Write neatly using a pencil. Do not cross out errors erase them. If you find yourself erasing extensively, stop and start again on a fresh page. If you must use a pen, do not scribble things out. Number your problems clearly and indicate what section they are from. Please CIRCLE or BOX your final answers. Always show your steps clearly. Simply writing the correct answers without showing how you arrived at them will earn you a zero on the assignment. Use a straight edge or ruler to draw graph axes. Label the following: the axes with an appropriate variable or title, each point plotted (using ordered pair notation), the equation of the curve next to its graph. Show your scale on the axes too. When doing word problems, you must define any variables you introduce and state your final answer in a complete sentence (or paragraph) that includes units. Simply stating that x = 3, for example, is not a satisfactory answer to a word problem. NOTE: You will earn a 0 on any homework assignment that is too hard to read; or if you seem to have mindlessly copied another student s homework; or if you allowed another student to mindlessly copy your work. To do well in this class it is essential that you do the homework daily. I expect you to spend about 10 hours each week on math homework, reading and studying. QUIZZES: We will have a short quiz at the beginning of class most Tuesdays, unless otherwise indicated. No make-ups will be given. I will drop your lowest quiz score when calculating your grade at the end of the quarter. Note: all electronic devices, including those that send or receive signals, must be turned off and put away during all quizzes unless there are explicit instructions to the contrary. EXAMS: There will be two in class exams this quarter - Tuesday, January 26 and Tuesday, February 23. I will NOT drop any exam scores, so it is vital that you are in class on these days. Put them on your calendar now! If you cannot make it to class on a day that we are having an exam, let me know (in person or via ) on or before the date of the exam. Make-ups will be scheduled to take place BEFORE the in-class exam whenever possible. If you miss either of these exams and do not make arrangements with me before the exam, you will receive a zero for that exam. Comprehensive final exams will be given at the following times: Section S2 (10:30a class) Wednesday, March 16 from 9:30a 11:20a; Section S3 (11:30a class) Friday, March 18 from 11:30a 1:20p. Failure to take the final exam will result in a course grade of 0.0. Note: all electronic devices, including those that send or receive signals, must be turned off and put away during all exams unless there are explicit instructions to the contrary. HOW DO I COMPUTE YOUR GRADE? GRADES: Two grading systems are available to you. The standard grading system is based on the following percentages: Homework 10%, Quizzes 30%, In-Class Exams 30%, and the Final Exam 30%. For those students who struggle with the material at the beginning of the quarter, but manage to understand it by the end of the quarter, I offer this alternate grading system: Homework 4%, Quizzes 6%, In-Class Exams 10%, and the Final Exam 80%. At the end of the quarter, I will compute your grade based on BOTH grading systems and record the BETTER grade. Decimal grades will be assigned for your performance in this class according to the table below. Decimal Grade Course % Decimal Grade Course % Decimal Grade Course % % % % % % % % % % % % % % % % % % % % % % % % % % % %

4 % % % % % 0.0 <58.7% % % Students wishing to be graded on the Pass/0.0 or Pass/NC systems must submit a P/NC Grade Option Request Form (signed by me) to the registration desk no later than Monday, February 8, POLICIES LATE WORK: Late work receives zero credit as I do not accept late assignments. Homework must be submitted at the beginning of the class period on the due date and no later. Other worksheets/assignments may be collected in class and will be due by the end of the class period. If you are going to be absent from class on the day that an assignment is due, you can either hand it in early, or scan it (or take pictures of it) and it to me by class time on the due date. It is YOUR responsibility to get all the materials to me on or before their due dates. CHEATING & PLAGIARISM: Cheating and plagiarism will not be tolerated in this class. Some of the work in this class is collaborative, and I expect you to use each other as resources. But for much of the required work, collaboration is not allowed. In particular, on exams, homework and quizzes, the work you submit must be your own. Any student appearing to compromise their work on exams, homework or quizzes may receive a zero for that assignment. In addition, the student(s) may be expelled from the course and receive a grade of 0.0. As defined by the College Policy Manual policy #5033: Academic dishonesty occurs when a student provides unauthorized academic benefits to another student or receives academic benefits he/she did not earn through his/her own efforts, by cheating or plagiarizing. Cheating includes, but is not limited to, conferring an unearned benefit to another student, copying another s work on an exam, preparing for an exam by using test questions from a stolen exam, accessing unauthorized materials, or turning in another person s work as one s own. WITHDRAWALS: If for any reason you decide to withdraw from this class, please contact me. If the withdrawal is completed on or before January 18, no record of the class will appear on your transcript. You will receive a W on your transcript if you withdraw between January 19 and February 17. To withdraw from the class after February 17, an emergency situation has to have taken place that has interrupted or interfered with your ability to attend class and perform course work. A written request for such an emergency withdrawal grade (or Z grade) must be provided before the end of the quarter. If you quit coming to class without officially withdrawing, you will automatically receive a V grade that will be computed as a 0.0 in GPA calculations. STUDENT RIGHTS AND RESPONSIBILITIES: Admission to Shoreline Community College carries with it the expectation that students will conduct themselves as responsible members of the academic community. This includes the expectation that students will obey the law; comply with the rules and regulations of the College; maintain high standards of integrity and honesty; respect the rights, privileges and property of other members of the College community; and will not interfere with College operations. Students are therefore expected to respect the rights of others to learn in a non-threatening, non-distracting environment. For more details consult the College Policy Manual, policy #5030. Students with physical or learning disabilities have the right to request and receive reasonable accommodations to ensure access to programs and facilities at Shoreline Community College. To receive reasonable accommodations, students are responsible for requesting accommodations and documenting the nature and extent of their disability in a timely manner. Students should direct their requests for accommodation to the Office of Special Services and Services for Students with Disabilities (FOSS 5226 or call or ssd@shoreline.edu). For more information regarding accommodations, see the College Policy Manual policy #5114. EMERGENCIES: If school is closed because of snow or another emergency, we will start where we left off when class resumes. That means that if we were scheduled to have an exam the day school is canceled, that exam will take place the first day back at school. If you cannot make it to school because of road conditions (regardless of whether or not school is canceled), please contact me and arrangements will be made to make up the work you missed. Listen to KIRO radio for a list of school closings, check the Shoreline CC webpage ( or call the main phone line to listen to the recorded message. Remember, we are not a member of the Shoreline public school district - we are Shoreline Community College.
