NettetTrigonometry. 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. Nettet4. okt. 2015 · Unless c 1, c 2 are both zero (hence θ 2 = θ 1 − π ), solution to (5) provides us with sin θ 1 and cos θ 1 (check that sin 2 θ 1 + cos 2 θ 1 ≡ 1 ). Together with (1) and (2) we can get the sin and cos of the other angle. Also, hence the system is symmetric, the solution is either { θ 1, θ 2 } or . Share.
