WebTrigonometry values of different ratios, such as sine, cosine, tangent, secant, cotangent, and cosecant, deal with the measurement of lengths and angles of the right-angle triangle. The values of trigonometric functions for 0°, 30°, 45°, 60° and 90° are commonly used to solve trigonometry problems.. Trigonometry values are all about the study of standard … The trigonometric functions of angles that are multiples of 15°, 18°, or 22.5° have simple algebraic values. These values are listed in the following table for angles from 0° to 90°. For angles outside of this range, trigonometric values can be found by applying the reflection and shift identities. In the table below, … See more In mathematics, the values of the trigonometric functions can be expressed approximately, as in $${\displaystyle \cos(\pi /4)\approx 0.707}$$, or exactly, as in $${\displaystyle \cos(\pi /4)={\sqrt {2}}/2}$$. … See more Some exact trigonometric values, such as $${\displaystyle \sin(60^{\circ })={\sqrt {3}}/2}$$, can be expressed in terms of a combination of arithmetic operations and square roots. Such numbers are called constructible, because one length can be constructed by compass and straightedge See more An irrational number that can be expressed as the sine or cosine of a rational multiple of π radians is called a trigonometric number. Since See more The values of trigonometric numbers can be derived through a combination of methods. The values of sine and cosine of 30, 45, and 60 degrees are derived by analysis of the 30-60-90 and 90-45-45 triangles. If the angle is expressed in radians as See more • List of trigonometric identities See more • Abramowitz, Milton; Stegun, Irene A., eds. (1972).
