WebFor every trigonometry function such as sin, there is an inverse function that works in reverse. These inverse functions have the same name but with 'arc' in front. (On some calculators the arcsin button may be labelled asin, or sometimes sin -1 .) So the inverse of sin is arcsin etc.

WebThere are three basic functions in trigonometry, each of which is one side of a right-angled triangle divided by another. The three functions are: You may find it helpful to remember Sine, Cosine and Tangent as SOH CAH TOA. Remembering trigonometric functions can be difficult and confusing to begin with. Even SOH CAH TOA can be tricky. WebTrigonometry (from Ancient Greek τρίγωνον (trígōnon) 'triangle', and μέτρον (métron) 'measure') [1] 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.
