In this topic, students will learn about functions, equations, and inequalities in high school level trigonometry and pre-calculus. Lessons will cover a range of topics including the unit circle, trig functions and their inverses, trig proofs, and radians. Students will also learn about rational functions and inequalities, as well as trig identities and computation. By the end of this topic, students will have a solid understanding of these foundational concepts in math.
