Unit 6 - Trigonometric Functions and the Unit Circle

Angles of Rotation and Radian Measure- Last thing we'll work on in Algebra 2 is how to find the arc length and different types of rotations to help prepare you for trigonometry. Are there other measurements for angles other than degrees? What about the right-hand rule, how does that work? Learn about this and more here!

Defining and Evaluating the Basic Trig Functions- Remember back in geometry when you learned a little bit about the trigonometric functions, and how they worked? Dive deeper into how they work here, and really understand how much easier it can be to work with these functions, instead of trying to solve on your own. Find out how here!
