Course Description

  • The trig functions of any angle are defined and applied to the solution of right triangles, oblique triangles, and vectors. Trigonometric identities and the graphs of the trig functions are studied. Each student is required to purchase and learn the efficient use of a hand-held calculator with trigonometric capabilities. Microcomputers are also used. (M) Prerequisite: MATH 128 or Mathematics Course B (3: 3, 0)

Course Objectives (and General Education Objectives)

  • Master algebraic manipulation techniques.  Sharpen problem-solving skills. 
  • We will learn how to read and extract information from diagrams, charts, and graphs. 
  • Be able to use mathematical models to help solve real-life problems.  Many real-life situations can be predicted accurately by mathematical functions.  We will experiment with some real-life applications and come up with valid, reasonable solutions.
  • Use the mathematical skills and analytical thinking skills that you have learned so far to meet any new, never-seen-before challenges.

Collected Assignment (if any)           

  • I usually don’t collect homework.  However, about 80% of the test questions come directly from the homework problems.  If I want to collect the homework, I will announce the due date in class.
  • I assign and collect worksheets.  These worksheets have very SPECIFIC due dates.  Late assignment (for any reason, sickness, trip, etc) will not be accepted. 

Unit Exams    

  • See scheduled dates for the five 50-point unit exams.
  • Your grade is calculated based on the best 4 out of your 5 exams (i.e. the lowest exam score is dropped.), plus any collected assignment points.
  • There is a 100-point comprehensive final exam. I will discuss the coverage of the final exam in class towards the end of the semester.  The final exam date will not be altered for any reason.
  • If you must miss the exam, contact me immediately.  I may choose to have you take the exam at a different time. The answer key is posted 48 hours after the test is taken.  No make-up exam will be given once the answer key is posted. 
  • You must read the instruction provided on the exam.
  • You may not use a cell phone for any reason during the exam.

Grading                     

  • Grade average formula:

 

  • Grading scale:

100-93=A

92-90=A-

 

 

89-87=B+

86-83=B

82-80=B-

 

79-77=C+

76-73=C

72-70=C-

 

69-67=D+

66-63=D

62-60=D-

59-0=F

Attendance

General:

  • Your attendance is required.  You are responsible for keeping up with the course work should you miss class for any reason. It is not my responsibility to reteach you the lesson.
  • Arriving in class between the first 5 to 20 minutes = 1 Late
  • Arriving in class after the first 20 minutes = 1 Unexcused Absence
  • 2 Lates = 1 Unexcused Absence
  • If we meet 3 times a week: Each lecture period is 1.0 hour.  5.0 up to 5.9 hours of unexcused absences will cause your final grade to be lowered by one letter grade.  For example, if your final grade is B+, it will be lowered to C+.  6.0 or more hours of unexcused absences will warrant an F for the course.
  • In case of severely bad weather, please check your Delhi e-mail for class cancellation.

 

Definition of Excused Absences:

  • Absences due to religious holidays ----You must notify me IN ADVANCE and show necessary literature.
  • Absences due to college sponsored academic or extracurricular activities ---- You must notify me IN ADVANCE and show necessary document such as team roster.
  • Absences due to DOCUMENTED medical reasons ----You must show a hospital admittance or discharge record, or a doctor's note in order to be excused from class. 
  • Extreme circumstances----such as sickness or death in the family, you must show documents such as a doctor’s note or obituary notice/funeral service program.  Show a dated car repair bill for absences due to car trouble.

Academic Honesty

  • Read the Student Handbook.
  • Any dishonest act on quizzes, worksheets, and exams will be reported.  All parties involved in the dishonest act will get a zero.  Second-time offenders will get an F for the course.

Classroom Expectations (Expectations on Professional and Mature Conduct)

·         Always bring your textbook, notebook, and calculator to class.  If you come without the required items, you will take an unexcused absence as a penalty.

·         Do not use your cell phone during class.  Please turn the ringer off during class.  If I see you text-message in class, you will be asked to leave the class and take an unexcused absence as a penalty.

·         Do not use profanities during class.  If I hear you use a swear word in class, you will be asked to leave the class and take an unexcused absence as a penalty.

·         Do not sleep during class.  The 2nd time I catch you sleeping in class, you will take an unexcused absence as a penalty.

·         Keep in mind that each lecture period is equivalent to a professional meeting. If a student does not comply with the Code of Student Behavior or with an instructor’s reasonable conduct expectations in the classroom, such non-compliance can affect the student’s evaluation and be cause for permanent removal from class or dismissal from College.

·         Food and colored drinks are not allowed in the classroom.  You may bring water with you.  If you have brought food items with you, please put them away or dispose them before class starts. Don’t leave trash behind

Accommodations

  • If you have certain needs and wish to be accommodated, see me and bring necessary documentations.
