Since you can state the values of the trig ratios in terms of x and y, and since you can see (on the circle) where x (for the tangent and secant) and y (for the cotangent and cosecant) are zero (being the axes). ). Since we can't divide by zero, …A unit circle is a circle on the Cartesian Plane that has a radius of 1 unit and is centered at the origin (0, 0). The unit circle is a powerful tool that provides us with easier reference when we work with trigonometric functions and angle measurements. You can apply the Pythagorean Theorem to the unit circle. 2. Long horizontal or vertical line =. √ 3. 2. For example, if you’re trying to solve cos. π. 3. , you should know right away that this angle (which is equal to 60°) indicates a short horizontal line on the unit circle. Therefore, its corresponding x-coordinate must equal.

Typically, we take r = 1. That is called the unit circle. The trigonometric functions in fact depend only on the angle θ -- and it is for that reason we say that they are functions of θ. Example 1. A straight line inserted at the origin terminates at the point (3, 2) as it sweeps out an angle θ in standard position.

The Unit Circle Lesson 13-2 Objective: Students will use reference angles and the unit circle to find the to find the sine and cosine values of an angle in Standard Position UNIT CIRCLE The "Unit Circle" is a circle with a radius of 1.
