Trignometric ratios of Specific Angles - Evaluating. Last updated at May 29, by Teachoo.

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.

I have noticed that students cannot actually remember values of six trigonometric ratios sin, cos, tan, cosec, sec and cot for 0. These values are used very often and it is recommended from my point of view that student should be able to tell the values instantly when asked. In this post our motive is to learn how to fill the table. Once, you learn to fill this table, you would be able to calculate any value in your mind.
