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.

We recall that we can evaluate trigonometric functions by sketching the argument in standard position and then determining the coordinates of the intersection between the terminal side of the angle and the unit circle. cheats ravioliWebIn trigonometry we use the functions of angles like sin, cos and tan. It turns out that angles that have the same reference angles always have the same trig function values (the sign may vary). So for example sin(45) = 0.707. The angle 135° has a reference angle of 45°, so its sin will be the same.
