Pre-calculus exposes students to a rigorous level of mathematics, essential to the study of UG level courses under Liberal arts and Sciences. The pace of the class and depth of the material may be different than those encountered in previous education. The focus of this course is primarily on various types of functions: polynomial, rational, exponential, logarithmic and trigonometric. The student will also learn about the behavior of functions through graphs and transformations; they will gain insight into the properties of these functions and their inverse forms. At the end of the course, students will be able to apply a variety of techniques to abstract and real-life problems alike. They will also use "Khan Academy Videos/ Resources" in this course in a blended learning and assessing approach.Course Objectives:Gaining factual knowledge (Essential) Learning fundamental principles, generalizations or theories (Important)Learning to apply course material (to improve thinking, problem solving, and decisions) (Important) Spring SemesterLearning Goals:Exponential and Logarithmic Functions One-to-One FunctionsInverse FunctionsExponential Equation/Function and its properties.Logarithmic Equation/Function and its properties.Applications of Exponential and Logarithmic FunctionsTrigonometric FunctionsTypes of Trigonometric FunctionsProperties of the Trigonometric FunctionsAnalytic Trigonometry Trigonometric Identities Sum and Difference FormulasDouble-angle and Half-angle Formulas Product to Sum and Sum to Product Formulas Systems of EquationsMatrix Algebra.Describing Data SetsCharacterizing Data.LEARNING OUTCOMESStudent Learning OutcomesMethod of Assessment1) Demonstrate the fundamental concept of a mathematical function and all of its properties.Quiz based upon class lecturer, Assigned homework exercises, and exam.2) Solve equations and inequalities both algebraically and graphically.Quiz based upon class lecturer, Assigned homework exercises, and exam.3) Find zeros of polynomials and the zero product property.

However, for two late attendances will be counted as one day absence. Three days of absence will result in the lose 60% of your marks. For example a student with 3 unexcused absences will receive an attendance mark of 2.Lesson Contribution/Class Participation – 10% The lesson contribution mark can be achieved by speaking at the board (50%), answering questions and other contributions (50%). 3. Assignments/ Homework – 10%Quizzes (20%) There will be three or four quizzes in Spring – one for each Chapter that is covered in Sullivan Pre-calculus. Each quiz will be equal in weighting. Mid-Term Exam (25%) The Mid-Term exam will test all of the content covered by the end of February. Final Exam (30%) The Final Exam will test all of the content covered by the end of Spring semester (April).KEY DATES & DEADLINESMid-Term Exam: Between 24th to 28th February.Final Exam: Between 22nd to 25th April.PLAGIARISM & ACADEMIC INTEGRITYAll members of the AUW Community are bound by the Academic Honor Code published in the Academic Bulletin (). The integrity of students’ academic work is very important to AUW faculty. Universities are based upon the fundamental principle that the work presented truly belongs to the author, because the academic community revolves around ideas and creativity. Each person’s ideas are his or her contribution to the academic community. Therefore, taking another person’s ideas and representing them as one’s own is a serious form of dishonesty. Similarly, cheating (copying someone else’s work, asking for answers, sharing answers, etc.) and other forms of dishonesty (falsifying data, making up references, etc.) are also serious breaches of this honor code.Plagiarism is intentionally or unintentionally taking credit for another’s words or ideas. You may not plagiarize in your academic work, and you must adhere to the following:When you use someone else’s words (whether they are from a distinguished author or a classmate’s paper), place the words you have copied in quotation marks and provide the appropriate citation of author and source. A good guideline to use to avoid plagiarism is to make sure quotes of three or more sequential words from someone else are put into quotation marks. If you paraphrase (reword) another person’s ideas, then you must also cite the source. Paraphrasing must involve changing the words and sentence structure of the original source. Cite materials you copy or paraphrase from the Internet, even if the author is not identified. The various academic disciplines (humanities, social sciences, sciences) use slightly different formats for footnotes, endnotes, and bibliographies. Your professor for a particular class will tell you which format he or she wants you to use in that class.Copying, asking for answers, sharing answers, and any other form of cheating (misrepresenting your own work and knowledge) on exams or quizzes are all forms of academic dishonesty.Other Forms of Academic DishonestyMaking up references, quoting wrong sources, etc. Falsifying data. Misrepresenting your situation to be excused from academic work. Submitting the same paper in more than one class. Informing a student in a later class about questions on tests or quizzes. Misrepresenting your academic work or qualifications in any way. STRATEGIES TO PREVENT PLAGIARIM& VIOLATIONS OF ACADEMIC INTEGRITY Students will not plagiarise –please see the Student Handbook.CLASS BEHAVIOURYou are expected to be in class on time.You should participate in class discussions and contribute to the class goal of learning Pre-calculus.Read your class notes over within 24 hours (or at least once before the next class).Students will complete all home works and assignments given by the required deadlines. Mobile phones and similar electronic devices such as MP3 players, laptops, and so on should be switched off and put away at the beginning of class. You will treat others in this class with respect.Students are expected to check their email at least twice daily, preferably in the morning and evening. Students are advised that a majority of faculty answer email within a 24 hour period during the week and a 48 hour period during weekends. Please be aware that students who do not check email regularly may miss important class announcements.
