- Grade 7+
This course covers intermediate and advanced trigonometry and precalculus concepts. You’ll learn trigonometry by actively engaging with videos, practice problems, and other online course materials with your instructor offering learning support and one-on-one review sessions along the way. Your knowledge will be assessed through homework, written assignments, quizzes, projects, and cumulative exams. By the end of this course, you’ll know how to apply trigonometry in any situation. Due to an overlap in content, students who have taken CTY’s Honors Precalculus course should not enroll in this course.
Recommended length of enrollment: 3 months
Time Commitment: 3-6 hours per week (1-hour optional meeting, 3-5 hours of independent work).
Students enroll in a course by selecting an open class below. Students progress at their own pace following course guidelines, with guidance from instructors who strive to meet individual needs.
