Trignometric ratios of Specific Angles - Evaluating.

The trigonometric functions relate the angles of a triangle to the length of its sides. Trigonometric functions are important in the study of periodic phenomena like sound and light waves and many other applications. The most familiar three trigonometric ratios are sine function , cosine function and tangent function. For angles less than a right angle, trigonometric functions are commonly defined as the ratio of two sides of a right triangle containing the angle and their values can be found in the length of various line segments around a unit circle. The angles are calculated with respect to sin, cos and tan functions which are the primary functions, whereas cosecant, secant and cot functions are derived from the primary functions. Here, you will learn the value for sin 90 degrees and how the values are derived along with other degrees or radian values.

There are two main ways in which trigonometric functions are typically discussed: in terms of right triangles and in terms of the unit circle. The right-angled triangle definition of trigonometric functions is most often how they are introduced, followed by their definitions in terms of the unit circle. Trigonometric functions can also be defined as coordinate values on a unit circle. A unit circle is a circle of radius 1 centered at the origin. The unit circle definition allows us to extend the domain of trigonometric functions to all real numbers. Refer to the figure below. Given a point x, y on the circumference of the unit circle, we can form a right triangle, as shown in the figure.
