Who's it for?
Anyone who needs help learning or mastering high school trigonometry material will benefit from taking this course. There is no faster or easier way to learn high school trigonometry. Among those who would benefit are:
- Students who have fallen behind in understanding the applications of trigonometric functions
- Students who struggle with learning disabilities or learning differences, including autism and ADHD
- Students who prefer multiple ways of learning math (visual or auditory)
- Students who have missed class time and need to catch up
- Students who need an efficient way to learn about trigonometric functions
- Students who struggle to understand their teachers
- Students who attend schools without extra math learning resources
How it works:
- Find videos in our course that cover what you need to learn or review.
- Press play and watch the video lesson.
- Refer to the video transcripts to reinforce your learning.
- Test your understanding of each lesson with short quizzes.
- Verify you're ready by completing the Trigonometric Functions chapter exam.
Why it works:
- Study Efficiently: Skip what you know, review what you don't.
- Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
- Be Ready on Test Day: Use the Trigonometric Functions chapter exam to be prepared.
- Get Extra Support: Ask our subject-matter experts any trigonometric functions question. They're here to help!

Students will review:
In this course, you'll learn the answers to questions including:
- What are sines, cosines and tangents?
- What are cotangents, secants and cosecants?
- How can I memorize the points and degree measures of the unit circle's first quadrant?
- How can I apply the unit circle?
- What are the properties of special right triangles?
- What are the trigonometric function values of special angles?
- How do I apply the laws of sines and cosines?
- What is the double angle formula?
- How do I convert between radians and degrees?
1. Trigonometry: Sine and Cosine
Sine and cosine are basic trigonometric functions that are used to solve for the angles and sides of triangles. Review trigonometry concepts and learn about the mnemonic used for sine, cosine, and tangent functions.
2. Practice Problems with Circular Trigonometric Functions
Circular trigonometric functions are the trig functions which are calculated using a circle. Learn more about the unit circle, degrees, and radians, and apply your understanding by working through example problems.
3. Trigonometric Function Values of Special Angles
All trigonometry is based on the right triangle, which is a triangle with one 90-degree right angle, and all trigonometric functions are ratios of the right triangle. Learn about right triangles, trigonometric functions, and values of special angles in trigonometry.
