Course Description: 4 hours lecture, 2 hours recitation (weekly); 4 credits
This course meets three times a week: twice for lecture sessions and once for a recitation section. In lecture, you will be presented with the topics and example problems together with a large group of students. In lecture, it will be important that you pay attention and take good notes. In recitation, you will take practice quizzes, practice doing the problems yourself, and compare notes with others in a smaller group. In recitation, it will be important that you ask questions about whatever you’re stuck on and attempt the problems your instructor gives you.
Topics include: review of basic algebra; inequalities; logarithmic, exponential, and trigonometric functions; graphs and equations; inverse functions; elements of analytic geometry. Introduction to the use of graphing calculators. Includes a review of selected topics from Intermediate Algebra.
Textbook: Algebra and Trigonometry, 4th Edition, by Stewart, Redlin, and Watson; Enhanced WebAssign Edition. Cengage Learning (2014). ISBN-13: 978-1305071742. We will cover Sections P.3-P.9, 1.3-1.8, 2.1-2.6, 3.1, 4.1-4.6, and 5.1-5.6.
Supplies
WebAssign account. Purchase this as soon as possible using the link in Brightsapce. You will need this in order to do the homework, and you will need to do the homework to follow along with the course.
A graphing calculator is required. The TI-84 is highly recommended.
Keep a binder, or notebook and folder for your lecture and homework notes.
Grading Policy:
60% Midterm Exams
25% Final Exam
10% Homework
5% Recitation Participation
Homework: Homework assignments will be posted and taken on WebAssign. Each homework assignment must be submitted through WebAssign by the listed due date. No late work will be accepted.
Midterm Exams: There will be three midterm exams and a final exam, all of which will be administered in lecture. The dates for the exams will be announced at least a week in advance. There will be no make-up exams. If you have a reason for missing an exam that is consistent with CUNY policy on missing class, email the professor about this as soon as possible.
There will be no opportunities for extra credit in this class.
Final Exam: There will be a comprehensive final exam at the end of the semester. The final exam cannot be rescheduled. Missing the final exam will result in an F or WU or INC grade for this class unless otherwise discussed. An INC (incomplete) grade may be given by the discretion of your professor if all your other course work has a passing grade. In the case of an INC grade, you need to clear it as soon as possible by making the necessary arrangements with your professor.
Attendance: Attendance will be recorded during each class session. Six or more unauthorized absences will result in a WU grade. In general, the only acceptable excuses for missing class (including exams) are serious illness, family/personal emergency, or religious observance. Appropriate documentation must be presented to authorize an absence.
Academic Integrity: Students are expected to uphold the CUNY Policy on Academic Integrity. Cheating on exams will result in failures, at minimum. For details on the school’s policy on this, see the Academic Integrity section of the Student Handbook.
Student Accessibility: Qualified students with disabilities will be provided reasonable academic accommodations if determined eligible by the Center for Student Accessibility. Prior to granting disability accommodations in this course, the instructor must receive written verification of student’s eligibility from the Center for Student Accessibility. It is the student’s responsibility to initiate contact with the Center for Student Accessibility staff and to follow the established procedures for having the accommodation notice sent to the instructor.
