Please ensure you provide me with an email address which you check daily.Required Text: Algebra & Trigonometry, 8th Edition, Sullivan, with “MyMathLab” package. Attempting to take this course without the textbook is not recommended!THE COLLEGE BOOKSTORE:Location:103 Ward Street Boston MA 02115Telephone:617-445-8814Learning ObjectivesAt the completion of this course, the student should be able to:Add, subtract multiply and divide real numbers, complex numbers, and polynomials with real coefficients.Compute using the laws of exponents, including nth roots.Factor any polynomial of degree two or less and certain higher order polynomials.Recognize, state, and solve linear and quadratic equations.Compute the distance and the midpoint between two points.Recognize and graph equations in two variables on a Cartesian plane.Recognize and graph (x − a)2 + (y − b)2 = c2 .Solve problems involving proportionality.Solve 2 × 2 systems of linear equations by substitution and by elimination.Recognize, compute with, and convert between decimal degrees, degrees/minutes/seconds, and radians.Compute sin θ, cos θ, tan θ, csc θ, sec θ, and cot θ for general angles θ.State and use both the law of sines and the law of cosines.Solve triangles, given sufficient data.Perform basic arithmetic on vectors including adding, subtracting, and multiplication by a scalar.Class Participation and Attendance:You are required to attend all classes and lab sessions. Attendance will be taken at the beginning of each class. Students arriving late for class will be marked as absent at the discretion of the instructor.Students missing more than 15% of scheduled classes (including labs) may be withdrawn according to WIT policy. If you miss a class it is your responsibility to ensure that you learn the material covered, do the homework set and check on any announcements that were made.Attendance bonus: Starting in week 2, if you never miss a single class then you will be awarded extra credit! 3 percentage points will be added to your final score if you don’t miss a class; for example, if you are at every single class and say your final average is 93%, then your average will become 96%.The drop/add period for day students ends on Friday of the first week of classes. Dropping and/or adding courses is done online. Courses dropped in this period are removed from the student's record. Courses to be added that require written permission, e.g. closed courses, must be done using a Drop/Add form that is available in the Student Service Center. Non-attendance does not constitute dropping a course. If a student has registered for a course and subsequently withdraws or receives a failing grade in its prerequisite, then the student must drop that course. In some cases, the student will be dropped from that course by the Registrar. However, it is the student's responsibility to make sure that he or she meets the course prerequisites and to drop a course if the student has not successfully completed the prerequisite. The student must see his or her academic advisor or academic department head for schedule revision and to discuss the impact of the failed or withdrawn course on the student's degree status.Homework:All homework and exam problems will closely follow examples provided in the class. Homework will be set using the MyMathLab system (more information on this will be given in class).IMPORTANT: Your MyMathLab Course ID for this class is: ridge22037Homework will generally be due twice per week, on Mondays and Thursdays. Classwork will be due at the end of the “lab” session in which it is set. I encourage a two-way conversation during the class – if there is something from a homework that you do not follow, please let me know. The “lab” sessions in particular are a chance to spend more time working through examples together.Make sure to seek help if you are struggling with any homework problems, either by email, phone or during office hours. Students are encouraged to work on homework problems together, but should remember that you won't have a friend to help you in the exam!Credit will not be deducted if you seek help, but you will almost certainly lose points if you are struggling with a topic and don't seek help! If you cannot do the homework problems, then you won't be able to do the exam problems either!Exams: Six exams will be given in this course: this includes the final exam and the five in-class exams before the final exam (see class schedule). When calculating your final score, your lowest in-class exam score is dropped. The final exam is compulsory and that score cannot be the one that is dropped.Calculators:Calculators and in particular, graphing calculators - are not required for Math 205. Calculators will not be allowed during quizzes or exams. They may be used to help complete certain homeworks.Makeup Policy: If you miss an exam, then the makeup policy is that you must have a medical excuse (verifiable via a doctor’s note or a phone number of the medical facility) or a special circumstance (funeral, etc.). Otherwise if you miss an exam, then that is a zero. Assessment and Grading:Grading of all in-class problems tests, and the final exam will require you to show your working. If you use the correct methodology to a problem, but do not get the correct answer, you will still get most of the points for that problem. Therefore, make sure to include every step of your working – a correct final answer will get zero points if you do not show how you got to it.Your final class grade will be calculated as follows:Cumulative homework average: 10% (missing problem sets count as a zero).Cumulative classwork (lab) average: 10% (missing labs count as a zero).Five in-class exams (Average will be calculated after dropping lowest score): 60%Final Exam: 17%Attendance bonus: 3%The following is the grading scale, as mandated by WIT policy:Letter GradePercent RangesA96%-100%A-92%-95%B+88%-91%B84%-87%B-80%-83%C+76%-79%C72%-75%C-68%-71%D+64%-67%D60%-63%FBelow 60% Course ScheduleAlgebra ReviewR.2 Algebra EssentialsR.4 Polynomials R.5 Factoring PolynomialsR.7 Rational Expressions R.8 nth Roots; Rational ExponentsIn-class test 1Linear and Quadratic Equations1.1 Linear Equations,1.2 Quadratic Equations 1.3 Complex Numbers 1.7 Problem Solving In-class test 2Graphs2.1 Distance and Midpoint Formulas2.2 Graphs of Equations in Two Variables 2.3 Lines2.4 Circles2.5 Variation 12.1 Systems of Linear Equations (2×2 only) In-class test 3Right Angle Trigonometry7.1 Angles and Their Measure, 7.2 Right Triangle Trigonometry7.3 Computing the Values of Trig.

Academic dishonesty includes cheating, inventing false information or citations, plagiarism, tampering with computers, destroying other peoples studio property, or academic misconduct (Academic Catalog). See your catalogue for a full explanation.Student Accountability Statement: Cheating on homework, a quiz, or an exam will result in a zero for that activity. Repeated cheating will be reported to the Institute and will result in an F in the class. Plagiarism is cheating. If you do not understand what plagiarism is in the context of a mathematics course, please come talk to me before you cross the line. To promote academic honesty, a random number of exams will be selected and photocopied before being returned to students. All exams and tests are closed book unless otherwise specified, so please put all your books, laptops, cell phones, ipods, etc... out of sight during tests and exams. Furthermore, talking or looking away from your paper during a test or exam is strictly prohibited. Leaving the classroom for any reason during a test isalso prohibited.Disability Services Statement:Any student who thinks s/he may require a disability-related accommodation for this course should contact the Disability Services Office as soon as possible. Disability Services coordinates reasonable accommodations for students with documented disabilities. They are located in Watson Hall 003 (the Counseling Center) and can be contacted at 617-989-4390 or counseling@wit.edu. Note that it is also your responsibility to contact us privately as soon as possible to arrange for such accommodations in a timely manner.
