MAT 104 Trigonometry Summer 2008
Instructor: Bruce Armbrust, phone: 541-4660 ext. 314, email: armbrust@ltcc.edu
Office Hours: I will be available in room A210 from 10:30 - 11:00 AM, Monday-Thursday.
Class Time and Location: Mon. - Thurs. 8:30 -10:20 AM, E106
Textbook: Precalculus, Michael Sullivan and Michael Sullivan, III
Calculators: A graphing calculator is required for this class. I will be demonstrating with the Texas Instruments-89. I will do my best to assist with other calculator models.
Course Description: MAT 104 covers trigonometric functions of real numbers and angles, their graphs and properties, functions of multiple angles, identities, reduction formulas, radian measure, inverse functions, solutions of triangles, polar coordinates, parametric equations, and complex numbers.
Prerequisite: Mat 103A with a “C” or better or equivalent or appropriate skills demonstrated through the math assessment process.
Corequisite: Mat 103B or equivalent or appropriate skills demonstrated through the math assessment process. Prior completion of Mat 103B with a grade of “C” or better also satisfies this corequisite.
Course Objectives: 1.
Provide and analyze graphs of trigonometric functions.
Course Grade: Your final letter grade will be based on the usual grading scale: A 90-100%, B 80-89%, C 70-79%, D 60-69%, F 0-59% The following items will make up the course grade: Homework: 150 points Quizzes: 200 points Exam1 (July 10): 200 points Exam2 (July 29): 200 points Final Exam (August 7): 250 points
You may check your grades at any point in the quarter by going to the following website:

Homework: Homework will be due the class period after it is assigned. Homework not turned in at this time will be considered late. You may turn in homework up to two class days after it is assigned for half credit. Your homework score will be determined in the following way: up to 5 points for completion and one point each for 5 problems chosen at random to be graded.
Quizzes: There will be five quizzes given over the quarter (July 3, 8, 17, 23, and August 4). Your lowest quiz score will be dropped. These quizzes will be designed to help prepare you for the exams, and quiz problems will be taken directly from the homework assignments. Since the lowest quiz score is dropped, you may not make up a missed quiz.
Exams: All exams will be given in two sections: one portion will allow calculators while the other will not. If you cannot make it to an exam you may take it up to 2 school days prior to the scheduled date with proper arrangements. Otherwise, a regular exam may be made up after the scheduled date with a penalty of 10% per day. The final may not be taken after August 7th.
Registration Information: You must register for this class at the Office of Admissions and Records. You may drop the class with no penalty or mark on your record on or before July 11. After July 11, you may drop the class and receive a grade of W until July 21. After July 21, if you are still enrolled, you will receive a grade of A, B, C, D, F or I.
How to Succeed in a Math Class: I am often asked how to successfully pass a math class, and here is my advice:
I) Come to every class session. Be prepared, and plan on participating. II) Do your homework. This is your chance to practice your skills, so be sure to take advantage of it. III) Read the book. You paid good money for it, so you might as well use it. IV) Make use of available tutors and stop by my office. You will find tutors who know the subject matter in this course in the MSC from 9:30 – 1:00 Mon. -Thurs. V) Do math every day. Math is just like everything else: if you don’t practice, you become rusty.
Note: Since the summer quarter is compressed and highly accelerated, you MUST keep up with the class. If you do not work on math everyday, you will fall behind. You will find that you may need to spend up to four hours outside of class each day to master the material. I strongly encourage you to make use of the tutoring center and come by my office to make sure that you are on top of the material.
Learning Disabled Students: Students with disabilities who may need accommodations for this class are encouraged to notify me and contact the Disability Resource Center (DRC) early in the quarter so that reasonable accommodations may be implemented as soon as possible. Students may contact the DRC by visiting the Center (located in room A205) or by phoning 541-4660, ext. 249 (voice) or 542-1870 (TTY for deaf students). All information will remain confidential.
Technology in the Classroom: All cell phones, headphones, MP3 players, iPods, etc, must be turned off and put away prior to the start of each class. No electronic devices (other than calculators) may be used during quizzes and exams.
Academic Dishonesty: Academic dishonesty of any form will not be tolerated. Students caught cheating on exams or quizzes will receive a score of zero on the assignment for the first offense and a course grade of F for the second offense. Students my work together on homework assignments (and, in fact, are encouraged to) as long as all students understand the material covered.
