Cos -60

Nel triangolo rosso in figura, il coseno di è dato da ⁡ = ¯. Più in generale, si definisce il coseno prendendo una circonferenza di raggio unitario e la semiretta uscente dall'origine che forma un angolo con l'asse delle ascisse come in figura. Il coseno dell'angolo è quindi definito come il valore della coordinata del punto di intersezione tra la prima semiretta e la circonferenza (in
