Math 1316_28144 Trigonometry

Course Description:
Topics include solutions of triangles, Euler Identity, graphing of trigonometric and inverse trigonometric functions, identities and trigonometric equations,and introduction to vector analysis.

Course Intent:
This course is intended for students whose curricular requires trigonometry as a prerequisite for higher mathematics courses.It may also be taken as a first course in trigonometry or as a review course. Students whose curricular are generally non-technical in nature may take this course as a mathematics elective if the necessary algebraic and geometric prerequisites have been met. The transferability of this course as either mathematics credit or elective credit is at the discretion of the school to which the student intends to transfer.

Prerequisite: A grade C or Better in Math 1314/ or an equivalent

20. Solve problems dealing with vectors.

Course Policies

1. Attendance:
Daily attendance will be taken. Students are encouraged to attend the classes regularly. You should not miss a class unless it is beyond your control. Students are responsible for the class notes and the announcements (absence is not an excuse). You will be subjected to administrative withdrawal of the course for excessive absences (Must be less than or equal to 12.5%. See the student hand book). That is the student will be dropped from the course after 6 hours of absences.
2. Classroom Maintenance
Please try your best to keep the classroom clean. After your class move chairs up to the tables/keep the desk in orderly manner, and remove any papers from the table or chair. Do not write on the tables.
3. Classroom Discipline
All students are treated as adults and will be responsible for their actions. Kindly observe the following rules for proper progress of the class.
(i). Please respect your neighbor's right to learn in a quite atmosphere. Kindly refrain from all unwanted chattering random irrelevant comments. You should actively participate the lesson by taking notes and asking questions to clarify doubts.
(ii). Try your best to be in the class on time. If you have to come late for some reason, please enter the classroom as quietly as possible without disturbing others.
(iii). Please do not leave the classroom early. You are responsible for all the announcements I make in the class. If you have some reason to leave early, please do it as quickly and discretely as possible, but do not forget to inform me in advance.
(iv).Cell Phone:
Turn off or keep it on vibrator during the class time. No student can answer the cell phone within the classroom. If your cell phone rings and / or answer the phone during the class time it is considered as tardy. Each tardy will cost you 5 point at next exam. If your cell phone vibrates you may answer it out side the classroom. But remember walk out as quietly and discreetly as possible.
4. Students with Disabilities:
Any student with documented disability (e.g. physical, learning, psychiatric, visual, hearing, etc.)who needs to arrange reasonable accommodation must contact the disability service office at their respective college at the beginning of each semester. The faculty is authorized to provide only the accommodation requested by the Disability Support services office. (See the student handbook.)
5. Homework:
Homework will be assigned regularly and will be collected only on the test day. Randomly selected ten questions will be graded. Maximum of 10 points will be added to the test grade for neatly written completed (perfect) homework.
6. Resource Materials:
Any student enrolled in Mathematics course at HCCS has access to the various MATH labs in the system.(HCCS Central Math lab: JDB 300) The math labs staffed with Mathematics faculty and student assistants, and offers tutorial help, video tapes and computer aided tutorials.
7. Examinations:
There will be 3 in-class tests and a comprehensive final examination. All students must take the final examination in order to pass the course. No calculators are to be used on graded course work and in particular all examinations.
8. Academic Honesty:
Any kind of attempt to cheat during an examination will result in the immediate seizure of the examination paper and an automatic zero on the examination. Any talking, attempting to see neighbor's work, referring to notes or books, during an examination will be considered as cheating. It can results dismissal from entire HCC system.(See student handbook)
9.INTERNATIONAL STUDENTS: Receiving a W in a course may affect the status of your student Visa. Once a W is given for the course, it will not be changed to an F because of the visa consideration. Please contact the International Student Office at 713-718-8520 if you have any questions about your visa status and other transfer issues.
10. NOTICE: Students who repeat a course for a third or more times may soon face significant tuition/fee increases at HCC and other Texas public colleges and universities. Please ask your instructor / counselor about opportunities for tutoring / other assistance prior to considering course withdrawal or if you are not receiving passing grades.
11. Make-up Examinations:
There will be no make-up exams for any reason. If you missed an exam due to valid reason such as illness attested by an attending physician, the final exam grade will be given to the exam you missed. Such a request has to be informed me by a written statement. Otherwise zero will be given to the exam you missed.
12. Grading Policy:
A student who take the final examination will receive, based on the course average A(100-90), B(89-80), C(79-70), F(60-0). The course average is computed as follows.

Course Average = 0.6(In-class Test Ave)+0.15(Quiz Ave)+0.25(Final Exam)
