Course Outline, Mathematics - Algebra 2-Trigonometry - Course Description: Algebra 2 is the study of equations of second degree, which include such diverse geometric manifestations as parabolas, ellipses, hyperbolas, and circles. We learn techniques to solve quadratic equations, as well as further techniques to solve systems of linear equations. Equations of the second degree have applications from astrophysics (planetary motion) to geometry (Pythagorean Theorem) to sports (how a basketball travels through the air). In addition, we study polynomial, rational, algebraic, and transcendental functions and important theorems such as the Fundamental Theorem of Algebra. The connection to circles and right triangles marks the transition to trigonometry, a subject that introduces angle measurement to the algebraic context of functions, equations, and graphs. Algebra 2 with Trigonometry will also be used to develop general skills of effective thinking, including imagination, abstraction, persistence, and active learning. All of these skills are increasingly necessary in our modern mathematical world, but are also timelessly valuable in understanding what the scientist Galileo called this grand book the universe, which stands continually open to our gaze it is written in the language of mathematics. Course Objectives: This course is intended to: 1. Help students truly understand the fundamental concepts of algebra, geometry, trigonometry, exponential and logarithmic functions, statistics and probability. 2. Foreshadow important ideas of calculus. 3. Illustrate to students how algebra and trigonometry can be used to model real-life problems. 4. Prepare students for the Geometry and Algebra 2/Trigonometry Regents exam. 5. Prepare students for upper level mathematics. Essential questions: 1. How do you determine the differences and similarities between the families of functions, (Exponential, Logarithmic, Quadratic, Polynomial, Rational, Trigonometric)? 2. Which problem-solving strategy is most appropriate in this situation? 3. How do I use my mathematical tools to create models for real-world situations and then solve them efficiently for a given set of conditions? 4. How does the unit circle relate to the trigonometric functions?

Graphing Calculator: TI-83 is recommended 4. Pencils, an eraser, a ruler (preferably a protractor), and a compass 5. Graph Paper 6. Notebook Composition book recommended 7. Folder or binder to keep quizzes, exams, and hand-outs. Course Requirements: 1. Notebook: Students strongly encouraged to take notes during class. Extra credit will be awarded to students who capture complete notes in an orderly manner. 2. Homework: Students will be assigned daily homework and encouraged to use the composition book. Homework assignments submitted past due date will not be accepted unless under extreme circumstances. Homework quizzes will be given weekly to ensure learning and homework completion. 3. Classwork: Participation in class assignments and discussions Group work/ projects 4. Tests and Quizzes: At least one-week notice will be given for tests and quizzes. There will be no make up quizzes or tests unless the instructor is informed in advance and an acceptable written note is provided with a justification for the absence. There will be no test revisions. 5. Pencil and eraser: Ink is not allowed on any assignment or test.
Classroom Expectations: 1. Respect yourself, your peers, your teacher, and the learning environment. 2. Timeliness and punctual attendance is expected and rewarded 3. Complete classroom activities within the allotted time to better prepare you for exams 4. Follow the homework assignments in the recommended format provided to you by your instructor 5. Be prepared for class, i.e. bring in all your learning tools daily. Grading Policy: Criteria for computing grades: Weight Exams 40% Quizzes 30% Homework Quizzes/ NEAT Notebook 20% Class Participation/Group Activity 10% Suggestions and Resources: 1. One-on-one with teacher: Students are encouraged to approach the instructor either immediately after school or via email. 2. Textbook reading assignments: Read each section before class discussion, then re-read as homework activities are assigned, and use this material to study for quizzes and exams. Inclass activities leverage textbook examples. 3. Homework assignments: Make an effort to figure out even the more challenging homework problems, try multiple times, even consider a break in between turns. Often the brain works it out while doing other things. ERHS Academic Honesty Requirement: Academic Dishonesty will not be tolerated and will result in automatic failure of Exam/Quiz/Project and disciplinary action will be taken. ------------------------------------------------------------------------------------------------------------------------- I have read and am aware of the grading policy for Mr. Gonçalves class.
