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. WebSep 14, 2016 · #sin t = -3/5#. Find cos t Use trig identity: #cos^2 t = 1 - sin^2 t# #cos^2 t = 1 - 9/25 = 16/25#--> #cos t = +- 4/5# Since t is in Quadrant III, cos t and sin t are both negative.
