**Unit Circle: Sine and Cosine Functions | Precalculus II** Defining Sine and Cosine Functions. Now that we have our unit circle labeled, we can learn how the [latex]\left(x,y\right)[ latex] coordinates relate to the arc length and angle.The sine function relates a real number [latex]t[ latex] to the y coordinate of the point where the corresponding angle intercepts the unit circle.More precisely, the sine of an angle [latex]t[ latex] equals the y ...

**What is the Unit Circle in Trigonometry? | Sciencing** A “unit” circle has a radius of 1. In other words, the distance from the center of the circle to any part of the edge is always 1. The unit of measurement doesn’t really matter, because the most important thing about the unit circle is that it makes many equations and calculations much simpler.

**Trigonometric functions ** The six trigonometric functions can be defined as coordinate values of points on the Euclidean plane that are related to the unit circle, which is the circle of radius one centered at the origin O of this coordinate system. While right angled triangle definitions permit the definition of the trigonometric functions for angles between 0 and radian (90°), the unit circle definitions allow to ...

**Trigonometry The Unit Circle** The Unit Circle. Since the trigonometric ratios do not depend on the size of the triangle, you can always use a right angled triangle where the hypotenuse has length one. You can place such a triangle in a Cartesian system in such a way that one vertex will lie on a circle with radius one. A circle having the radius one is called a unit circle.

**Mathwords: Inverse Tangent** Do we choose 135°, –45°, 315° , or some other angle? The answer is –45°. With inverse tangent, we select the angle on the right half of the unit circle having measure as close to zero as possible. Thus tan 1 (–1) = –45° or tan 1 (–1) = –π 4. In other words, the range of tan 1 is restricted to (–90°, 90°) or .
