Formulae for twice an angle. Formulae for triple angles. The Chebyshev method is a recursive algorithm for finding the nth multiple angle formula knowing the th and th values. can be computed from , , and with WebTrigonometry. 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.

WebSecant (sec) - Trigonometry function. (See also Secant of a circle ). In a right triangle, the secant of an angle is the length of the hypotenuse divided by the length of the adjacent side. In a formula, it is abbreviated to just 'sec'. Of the six possible trigonometric functions, secant, cotangent, and cosecant, are rarely used.
