## Math 150 Trigonometry

### SYLLABUS OF FALL 2012 SEMESTER Lecture: Mondays & Wednesdays, 1:30−2:20 p.m., 101 Cardwell Hall Course Coordinator: Gabriel Nagy Email: nagy@math.ksu.edu Course Web page: www.math.ksu.edu/math150/fall-2012/

OBJECTIVE: Trigonometry is the field of mathematics concerned with the relationship between the angles and sides of a triangle.  Applications range across all areas of science and date back many centuries. Specifically, the study of  geography, astronomy, and engineering heavily rely on the tools of trigonometry.  Trigonometric functions are used to model continuous periodic motion, and provide excellent examples of the fundamental principles of Calculus.  For the university student, a strong foundation in trigonometry is crucial preparation for the study of calculus and higher mathematics.

TEXT: Fundamentals of Trigonometry, by Earl W. Swokowski and Jeffrey A. Cole, 9th Edition, 1999.

CALCULATOR: Calculators will be permitted during the exams, but all work needs to be shown to earn full credit.  For some of the exam and homework problems you may need the use of a calculator with keys equivalent to the following:  sin, cos, tan, INV, and yx. Most of the relevant calculations for homeworks can probably also be done using Google calculator.

CLASS FORMAT: Each week there will be two lectures, on Mondays and Wednesdays from 1:30 p.m. to 2:20 p.m. in 101 Cardwell Hall. In addition, you will be expected to attend a recitation session on Tuesdays.

EXAMINATIONS: There will be three exams during the semester on the following Thursday evenings from 7:15−8:15pm: September 13, October 11, November 8. The exam locations will be announced in class and posted on the bulletin board in the hallway across from Cardwell 125, as well as on the webpage. The final exam is on Thursday, December 12, 11:50am−1:40pm in a location to be announced later.   You may bring to each exam one sheet of 8 1/2 by 11 inch paper, with whatever notes, equations or formulas you wish to write (written on both sides).   You need to bring writing instruments (pens or pencils and an eraser), your KSU identification card, your one sheet of notes, and a calculator to the exams.  No books or cell phones will be permitted.
Missed exams: If you expect to miss a midterm exam for a legitimate reason (illness or hospitalization, for example), please notify your instructor as soon as possible. If your instructor deems the absence excusable then your other exams will be weighted to make up for the missing one; otherwise your score on it will be zero.There will be no make-up exams. A grade of incomplete may be given to a student who has missed more than one midterm or the final exam, if verifiable circumstances warrant it. It is your responsibility to discuss the situation with your recitation instructor should your personal situation suggest this as a possibility.

HOMEWORK: The homework schedule is posted on the Web at http://www.math.ksu.edu/math150/fall-2012/schedule.html. (This link is also accessible from the course web page, as well as from your k-state.online page.) Each homework assignment (written or online) is scaled to a maximum of 10 points.

• Online homework is due on Fridays by 11:59 p.m. This assignment is graded by the computer and you will know your score immediately. The online homework page is at http://www.math.ksu.edu/onlinehw/m150 and has separate links for each online homework assignment. You may attempt the online problem sets, as many times as you want (in the time alloted). You will receive your highest score over all your attempts. On each attempt you have two tries (after the first try, the computer markes the answers as right or wrong, and you will have a chance to correct any wrong answers before you resubmit your work for grading.)

TIPS FOR SUCCESS: Generally, students perform best in mathematics classes when they work consistently. You must study this course every day. You are developing a skill; no one would expect to become good at tennis if he/she only played once a month. Trigonometry is a moderately difficult college math class. The difficulty of the material increases as the course progresses. Many students may think, after the first couple of lectures, that one can get away without studying constantly or coming to the lectures. Typically such an attitude is a recipe for disaster.
Keys to success:

• Before lecture, preview the relevant section of the text and attempt to work the assigned problems.
• After lecture, review the text more carefully, comparing it to the notes you took in lecture. Work all homework problems (before recitation!). While doing this, consult the examples in the text and carefully read the material explaining them.
• Before Exams, re-read the chapter(s) from the book and your lecture notes, and re-do old homework problems, as well as all problems from the textbook, which are similar to them. If additional sample exam problems are provided by your instructor, work on them too. Attend the Exam Review lecture.
• Visit your instructor during office hours and/or sit in a Help Session. Ask about poorly understood points as soon as possible.
