TOPICS: Trigonometric functions and their inverses, solving triangles, trigonometric identities and equations, graphing.
PREREQUISITES: Satisfactory performance on the math placement exam, two years
of high school algebra, one year of high school geometry, or enrollment in Math 140.
TEXTBOOK: Precalculus, 7th edition, by Michael Sullivan, published
by Prentice Hall, 2005, with Study Pack (includes Student Solutions Manual, CD Lecture
Series, and access code for the Prentice Hall Tutor Center), ISBN #0131517503.
Textbook packages will be available through the Iowa
State University Bookstore online at http://www.isubookstore.com
or by telephone at 1-800-478-0048.
(As another option, you may buy a used copy of the
6th edition of the textbook if you want. Homework assignments will be available for
both editions. If you decide on this option, you should also buy the Student Solutions
Manual for the 6th edition.)
COURSE STRUCTURE: This combined section of Math 141-142 will operate as a
self-paced, web-based course with no formal lectures, offered through the Extended
and Continuing Education office.
Units: The course is divided into 6 units which you will have to complete consecutively. A detailed syllabus and directions for the completion of each unit will be given on the course web site (see the Detailed Schedule page for Math 141). Instruction for each unit will be provided by readings from the textbook, homework problems from the textbook, and supplementary material available online and via CD-ROM. To complete the unit, you must take the Unit Pretest and the Unit Exam.
Final Exam: There will also be one comprehensive Trigonometry Final Exam at the end of the course.
All graded exams are taken over the World Wide Web, and the Unit Exams and the Final Exam must be taken in the presence of a designated proctor (see the proctor instructions for details). However, you can take the Unit Pretests and take practice Unit Exams from home or anywhere else on the web. See the Online Testing page for specific details and rules concerning online exams.
There will be deadlines imposed for the completion of each unit, and the deadline date for the Trigonometry Final Exam is also fixed, but in all other respects you will be able to work at your own speed. Thus, depending on your background and workload, you may be able to proceed quickly through the course.

email and fax, and through the Prentice
Hall Math Tutor Center. Additional advice and help resources are given on the
Help page.
IS THIS COURSE FOR ME? This course may be appropriate for some students, and
perhaps not for others. A student taking this course must be self-motivated and must
actively seek help when needed. The course may be especially beneficial for students
who have learned the material before and just need a review, and also for students
who are simultaneously taking Calculus. Students who have trouble learning in a large
lecture format may also benefit from this approach. Students who have never taken
trigonometry may find the usual in-class format a better choice, but even in this
case exceptionally self-motivated individuals should be able to take the self-paced
version. The eLearner
web site has some helpful information for students planning to take a course on the
web.
This self-paced class has run for several years, and it has worked well for most students, especially those who followed the study guidelines and did not fall behind schedule. You may be interested in some grade distributions and comparisons from previous semesters of Math 141 and 142.
USE OF CALCULATORS: A good graphing calculator is required. The calculator
must be able to do parametric plots in addition to usual plots of functions, and
should be able to solve equations numerically (i.e., find intersections of curves).
My own recommendation for this course is the TI-83+, which is an excellent, easy-to-use
calculator that meets these requirements. However, many other calculators also meet
the above requirements and will work fine in this course.
DISABILITIES: Any student who feels that s/he may need an accommodation based
on the impact of a disability should contact
the instructor as soon as possible. The student will also need to obtain a Student
Academic Accommodation Request (SAAR) form from the Disability Resources (DR) office
(515-294-6624). Every effort will be made to meet accommodation requests. However,
because this course uses online assessment exclusively, some types of accommodations
may not be possible. In addition, no retroactive accommodations will be provided.
