Course Information

Course Description:

Course name College Trigonometry; Course number MATH 103; 5-credits
Class "103A": section D01D, item #3667
Class "103B": section D02D, item #3668

Dates: 4/3/2023 – 6/13/2023 including the final examination.

Format: This is a fully online course conducted asynchronously in Canvas and MyMathLab. This is NOT a "remote learning" format, thus has no real-time class meetings (ie. NO Zoom). FAQ - What's the difference between online and remote class? What does "asynchronous" mean?


Intermediate Algebra (Clark's Math 095) passed with a grade of at least "C" or qualifying score on the placement test satisfies prerequisite to Math 103.

College Trigonometry (Math 103) and College Algebra (Math 111) can be taken in either order, or simultaneously, but the Mathematics Department strongly recommends that you take Math 111 before Math 103 to learn functions in general before applying those concepts to the specific trigonometric functions.

Note: Clark's Math 096 does not satisfy prerequisite to Math 103. If you took Math 096 not 095, take Math 110 instead of Math 111, then take Math 103. Earning a "C" or higher in both 110 and 103 or in both 111 and 103 will qualify you for Calculus I, Math& 151.

In summary, the recommended order is to take 095 > 111 > 103 > 151 or 096 > 110 > 103 > 151.


Trigonometry focuses on trigonometric functions and their graphs. It includes trigonometric ratios, inverse trigonometric functions, right triangle trigonometry, circular functions, radian measure, graphs of trigonometric functions, trigonometric identities, trigonometric equations, laws of sines and cosines, 2D vectors, polar coordinates, polar and parametric curves, and applications of trigonometry.

This precalculus course is a challenging technical course primarily intended for those in STEM (science, technology, engineering, mathematics) majors. Together with College Algebra it forms the preparatory courses for the four-term Calculus-for-STEM sequence. Only those needing to take Calculus I (MATH& 151) or specifically wanting to learn precalculus topics should enroll. If you are just needing to earn a college-level math credit, then 103 and 111 are likely not the best courses to take (107 or 146 are good options).

The goal of this course is not only to learn precalculus material, but also to improve your critical thinking and problem solving abilities. The quantitative skills requirement [Q] of the general education distribution is met by this course.


The Mathematics Department has identified the following Course Level Outcomes for which you should be proficient upon successful completion of this course.

College Trigonometry Outcomes

  1. Evaluate the trigonometric functions at standard angles measured in degrees or radians, without the use of a calculator.
  2. Demonstrate understanding of the various definitions and properties of the six trigonometric functions and their inverses.
  3. Connect the graphical and symbolic representations of transformations of the trigonometric functions.
  4. Use identities to verify trigonometric identities or to simplify trigonometric expressions.
  5. Use trigonometric functions to solve application problems involving triangles, and interpret the solutions.
  6. Solve equations involving trigonometric functions.

How will you be assessed on these outcomes? See Mathematics Online Syllabus: Outcomes Assessment.

Course Materials

MyMathLab Platform and e-Textbook:

Icon indicating important information. FDDA to course materials: This is a First Day Digital Access (FDDA) course meaning that you already paid for the e-textbook and access to MyMathLab with your tuition. There is nothing more to purchase! You will have access to the e-textbook and MyMathLab on the first day of the quarter inside your Canvas course. If you drop the course by the first week drop deadline you will receive a full refund for the course materials.

What is MyMathLab (MML): MyMathLab access is required to access the tests. MML is a digital learning platform (DLP) provided by the textbook publisher, Pearson. In MML you can read the e-textbook, watch video tutorials, work interactive practice problems, complete assignments, and take tests. The complete textbook is included as an online e-textbook inside MyMathLab and also available through Pearson's e-book app.

e-Textbook that is included inside MyMathLab:

Trigonometry (12th edition)
by Lial/Hornsby/Schneider/Daniels
ISBN 9780135924136

Icon indicating important information. Registering in MyMathLab: You *must* register for MML using the "FDDA" link in our Canvas classroom. You do not need a "course ID code", in fact one won't work because MML is synced with Canvas.

Purchasing a Loose-Leaf Textbook: We'll be using the online e-textbook inside MyMathLab, but if later you find you need a print textbook from which to study, a fairly cost effective option is to purchase a loose-leaf version for $60 (free shipping).

Using a different textbook or older edition for study: If you already have a different trigonometry textbook that you connect well with, certainly use it to study from. An older edition of the physical textbook is also fine to use to study from as the chapter structure rarely changes from edition to edition (and may save you money if you plan to buy a physical textbook). Either way you are still required to have MyMathLab access since assignments and tests are conducted there.

Tutorial Videos: Videos are provided by Pearson linked directly in the e-textbook. Additional videos are linked in the supplementary resources portion of the professor's Lesson Notes. Sources for other recommended videos are listed at FAQs: Tutorial video sites. Note: please AVOID Khan Academy and do not recommend it in discussion posts.
