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.

WebUse a sum or difference formula to find the exact value of cos 165°. Solution 165° is not a special angle on the unit circle, but 165° = 135° + 30°, which are both special angles on the unit circle. So the sum formula for cosine can be used where u= 135° and v= 30°. $$\cos 165° = \cos\left(135° + 30°\right)$$ WebTo solve a trigonometric simplify the equation using trigonometric identities.
