Math 150 – Plane Trigonometry
Spring 2013
Coordinator and Lecturer: Professor Craig Spencer, Cardwell 046A, cvs@ksu.edu
Recitations Instructors: Everyone will have a recitation instructor that they will meet during their
first recitation class. Your recitation instructor will hold regular office hours and reply to your questions
via email. Since there are roughly 150 students in the course and only 30 students in each recitation,
your questions should first be directed at your recitation instructor before contacting Professor Spencer.
For questions about course procedures, please make sure that the answer is not already on the syllabus
or K-State Online before contacting your instructor.
Textbook: Fundamentals of Trigonometry (9th Edition), by Swokowski and Cole
Calculator: It is recommended that you have a calculator to use on the homework and exams, but all
work needs to be shown for full credit.
Web Site: http://www.math.ksu.edu/math150/spring-2013/
This site will contain information relevant to our class, and material such as lecture notes, grades, and
announcements will be posted on K-State Online. In the event of a school closure, revised information
and an updated syllabus will be posted on both the web site and K-State Online as soon as possible.
Prerequisites: The prerequisite for this class is College Algebra (Math 100). See Chapter 1 of our
textbook for a review of this material.
Class Format: This course is organized along the lecture-recitation method. Each week you are expected to attend two lectures (Monday and Wednesday) and one recitation class (Tuesday). The sections
to be covered in each lecture, along with the corresponding exercise sets, are indicated on the attached
schedule. You should read through the appropriate sections in the book before each lecture and, after
each lecture, reread the material and do as many of the assigned exercises as you can. Try to get the
remaining exercises worked in your recitation class, but one way or another, you should eventually have
all of the assigned exercises solved. Attending all classes, thoroughly reading the book, and doing lots of
problems (even more than the homework assignments if you have time) will be the best way to do well on
the exams. Since the class is cumulative, try not to fall behind, and seek help if you do not understand
something.
Math Tutoring Resources: See http://www.math.ksu.edu/courses/help/
In addition to asking your recitation instructor questions during their office hours or by sending them
email, help sessions are held most days in Cardwell Hall 041. Several instructors will be present to help
you, and a schedule can be found at the above web address. The page also includes links to information about other free tutoring resources available on campus. A list of individual paid tutors for Plane
Trigonometry are available from the Mathematics Department in Cardwell 138.
Grading Policy: Your grade for this course will be determined by the following:
Exam 1
10%
Written Homework 15%
Exam 2
15%
Online Homework 15%
Exam 3
15%
Recitation Grades 5%
Final Exam 25%
The overall grade thresholds for the course will not be set any higher than 90% for an A, 80% for a B,
70% for a C, and 60% for a D. However, depending on the overall grade distribution of the class and the
difficulty of the exams, these thresholds may potentially be lowered.
Exams: Students will be required to bring their student ID card to the exams. Students may use a
calculator and one 8.5”×11” sheet of notes on the exams. Note that cell phones (even in calculator
mode) and textbooks will not be allowed on the exam.
If you miss or expect to miss a midterm examination for a legitimate reason (for example, a serious illness
or representing K-State at a competition), then notify your recitation instructor as early as possible. Note
that booking personal travel without looking at the exam dates first is not considered a valid reason.
If your recitation instructor excuses your absence from a midterm exam, then your score on that exam
will be a weighted average of your other exam scores. If your recitation instructor does not excuse your
absence from a midterm exam, then your score on that exam will be zero. There will be no make-up
exams. If you miss more than one midterm exam or the final exam, for verifiable personal emergencies,
then it is possible to receive the grade of Incomplete for the course. It is your responsibility to work out
the details with your recitation instructor before final grades are established.

Written Homework: Written homework is due Wednesdays at 5 PM in your recitation instructor’s
homework box near Cardwell 120. Write your name and your recitation instructor’s name at the top of
the front page and staple your homework. Late homework will not be accepted, but each student’s lowest
two hand-in homework scores will be dropped.
Online Homework: http://www.math.ksu.edu/onlinehw/m150/
Online homework sets are due Fridays at 11:59 PM. Note that for some weeks, multiple online homework sets are due. Each student will receive different (but similar) assignments. Log on using your
K-State eID. You can retake the quizzes as many times as you want (before the due date). You will
receive your highest score over all your attempts. You do not have to answer the questions during the
session (you may print them out and work them at your convenience, or save your work then log back in
later). The first time your answers to a particular problem set are submitted, they are marked right or
wrong, and you will have a chance to correct any wrong answers before you resubmit your work. After
the work has been resubmitted, your work will be graded and you will be given the correct answers and
links to see how to work the problems. Late homework will not be accepted, but each student’s lowest
two online homework scores will be dropped. If you have issues with the Online Homework system, please
contact onlinehw@math.ksu.edu (for system errors) or your recitation instructor (for math help).
Recitation Grades This score will be determined by your recitation instructor. He or she will describe
how they will determine this grade during the first recitation.
Useful Drop Dates: February 11 - last day with a 100% refund, February 18 - last day with a 50%
refund, February 26 - last day to drop without a W being recorded, April 1 - last day to drop with a W
being recorded
Statements for Academic Accommodations for Students with Disabilities: Any student with a
disability that needs a classroom accommodation, access to technology, or other assistance in this course
should contact Disability Support Services (dss@k-state.edu) and/or their instructor. Disability Support
Services serves students with a wide range of disabilities including, but not limited to, physical disabilities, sensory impairments, learning disabilities, attention deficit disorder, depression, and anxiety.
Statement Regarding Academic Honesty: Kansas State University has an Honor System based on
personal integrity, which is presumed to be sufficient assurance that, in academic matters, one’s work
is performed honestly and without unauthorized assistance. Undergraduate and graduate students, by
registration, acknowledge the jurisdiction of the Honor System. The policies and procedures of the Honor
System apply to all full and part-time students enrolled in undergraduate and graduate courses oncampus, off-campus, and via distance learning. The honor system website can be reach via the following
URL: www.ksu.edu/honor. A component vital to the Honor System is the inclusion of the Honor Pledge
which applies to all assignments, examinations, or other course work undertaken by students. The Honor
Pledge is implied, whether or not it is stated: “On my honor, as a student, I have neither given nor
received unauthorized aid on this academic work.” A grade of XF can result from a breach of academic
honesty. The F indicates failure in the course; the X indicates the reason is an Honor Pledge violation.
