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. To define the sine function of an acute angle, start with the right-angled triangle ABC with the angle of interest and the sides of a triangle.
