Course Information

Course Description:

Class "103A": College Trigonometry MATH 103, section D01D, item #1554, 5 credits
Class "103B": College Trigonometry MATH 103, section D02D, item #1555, 5 credits

Dates: 1/4/2021 – 3/16/2021 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).

Coverage: 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 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.


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 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, Math& 151.

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


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 Software and e-Textbook:

Icon indicating important information. MyMathLab access with included e-textbook is REQUIRED. Physical textbook is OPTIONAL.

MyMathLab (MML) access is required to access the tests. MML is an online course delivery system provided by the textbook publisher. In MML you can read the complete textbook online, watch video lessons, work interactive tutorial exercises, and take tests. The complete textbook is included as an online textbook inside MyMathLab.

Icon indicating important information. For MML registration directions, please see information provided on first day of class in Canvas. Do not try to register with MyMathLab directly at the Pearson website, it won't work!

e-Textbook that is included inside MyMathLab: Trigonometry (12th edition) by Lial/Hornsby/Schneider/Daniels, ISBN 9780135924136.

Purchasing a Loose-Leaf Textbook: We'll be using the online 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 $50 (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 the tests are conducted there.
