WebThe trigonometric value is a collective term for values of different ratios, such as sine, cosine, tangent, secant, cotangent, and cosecant in a trigonometric table. ... Example 1: … 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 $${\displaystyle a\pi /b}$$, this takes care of the case where a is … 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 The trigonometric functions of angles that are multiples of 15°, 18°, or 22.5° have simple algebraic values. These values are listed in the … 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 • Abramowitz, Milton; Stegun, Irene A., eds. (1972). Handbook of Mathematical Functions with Formulas, Graphs, and Mathematical Tables. … 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 • List of trigonometric identities See more
