Thinkwell's Trigonometry Thinkwell's Trigonometry provides a comprehensive high school trigonometry course through video instruction, interactive practice, and built-in assessment tools. Taught by award-winning professor Edward Burger, the course helps teens develop a strong understanding of trigonometric concepts while building the mathematical foundation needed for precalculus, calculus, physics, and other STEM studies. Video lessons guide teens through topics such as angles and radian measure, trigonometric functions, graphing sine and cosine functions, inverse trigonometric functions, trigonometric identities, the Law of Sines, the Law of Cosines, vectors, complex numbers, and polar coordinates. The course also reinforces key algebra concepts and explores exponential and logarithmic functions, conic sections, and mathematical modeling. Professor Burger's clear teaching style helps teens understand not only how mathematical procedures work, but why they work. Interactive practice exercises provide immediate feedback, allowing teens to identify mistakes, strengthen understanding, and build mastery as they progress through the course. Automatically graded exercises, quizzes, chapter tests, practice tests, a midterm exam, and a final exam provide regular assessment throughout the year. The course includes progress-tracking tools, automatic grading, and additional course resources that support both independent learning and parent oversight. Parents can monitor performance without additional grading or record-keeping. Because the course is self-paced, teens can spend additional time on challenging concepts or move more quickly through familiar material. Twelve months of access gives families the flexibility to adapt the course to their homeschool schedule. For teens preparing for precalculus, calculus, physics, engineering, and other STEM fields, Thinkwell's Trigonometry provides a strong foundation in mathematical reasoning, problem-solving, and advanced mathematics.
