Welcome! This is a self-guided study aid for Trigonometry.
This resource uses the free OpenStax Precalculus textbook (link). If you wish to use an online homework system for practice, questions are available through Wiley Knewton Alta ($10.95/month as of August 2023 - link for current pricing information).
The Wiley Knewton Alta homework provides an adaptive experience, giving you questions that meet your individual learning path and a robust help system. You can choose to, however, work through questions available in the textbook for free.
So - let's get started! Click on the link to the textbook to see what is available. If you decide to use the online homework, click here and enroll in the monthly option.
The "General Trigonometry Resources" table has some general information that you can use through this resource as well as in future Calculus classes.
There are separate sections for different topics with individual videos as well as the online homework that is associated with it. Since this is a self-paced, stand-alone course, you can choose to work on the topics as you wish.
