In this lesson, we'll draw angles in standard position, convert between degrees and radians, find coterminal angles, find the length of a circular arc, and use linear and angular speed to describe motion on a circular path.

In this lesson, we'll use right triangles to evaluate trigonometric functions; find function values for 30°, 45°, and 60°; use equal cofunctions of complementary angles; use the definitions of trigonometric functions of any angle; use right triangle trigonometry to solve applied problems.

In this lesson, we'll find function values for the sine and cosine of 30 degrees, 45 degrees, and 60 degrees; identify the domain and range of sine and cosine functions; find reference angles; and use reference angles to evaluate trigonometric functions.

In this lesson, we'll see how secant, cosecant, tangent, and cotangent relate to the unit circle, we'll use properties of even and odd trig functions, we'll recognize and use fundamental identities, and we'll evaluate trig functions with a calculator.

A cheat sheet of all of the important topics from this unit.
