This handout will describe unit circle concepts, define degrees and radians, and explain the conversion process between degrees and radians. It will also demonstrate an additional way of solving unit circle …

We will soon learn how to apply the coordinates of the unit circle to find trigonometric functions, but we want to preface this discussion with a more general definition of the six trigonometric functions.

The Unit Circle -The unit circle is a very useful tool that is used often by math, physics, and engineering students to calculate the values of various trigonometric functions.

Complete Unit Circle of Trigonometry: Thus by remembering the first quadrant cosine and sine of these common angles, we can compute the cosine and sine of all the corresponding angles around the …

Reference angles can be used to find the sine and cosine of the angle when is not an acute angle anymore. Reference angles can also be used to find the coordinates of a point on a circle. Special …

During this unit, students will be learning about all of the components of the unit circle, strategies to remember these components, and how these components will help us later in our understanding of …
