WitrynaTrigonometry. Trigonometry (from Ancient Greek τρίγωνον (trígōnon) 'triangle', and μέτρον (métron) 'measure') is a branch of mathematics concerned with relationships between angles and ratios of lengths. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies.

Witrynap(y) = y 2 + sin(x) 2 - 1 = 0, would also be algebraic. However, that means e ix = cos(x) + isin(x) is algebraic as it's represented by arithmetic from algebraic numbers. That means any rational power (e ix) r = e irx of it also is. But if x isn't 0 then rx can be any rational number - that means e ir is algebraic for any rational argument! In ... WitrynaAlso, since sin(x) equals the square root of 1–cos(x) 2, the former can be rational only if 4-N is a square integer, which implies (since the square roots of 2 and 3 are not rational) that the only suitable values of N are 0, 3, and 4, which correspond to the arguments (up to sign) π/2, π/6, and 0 respectively. The sines of each of these ... herm malloyThe trigonometric functions of angles that are multiples of 15°, 18°, or 22.5° have simple algebraic values. ... If an angle is a rational multiple of ...
