WebTrigonometry (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. The Greeks focused on the calculation … WebMar 16, 2024 · And we follow these steps Put y = cos -1 (1/2) So, cos y = 1/2 Now ignore the signs and find value of θ Using the table, Find principal value according to the table
