You can calculate the value of the ratio of cos(60) = adjacent / hypotenuse by taking a equilateral triangle, and bisecting the top 60 degree angle into two 30 degree angles creating two 30,60,90 degree triangles. The Cosine function ( cos(x) ) The cosine is a trigonometric function of an angle, usually defined for acute angles within a right-angled triangle as the ratio of the length of the adjacent side to the hypotenuse. It is the complement to the sine.

Cos -60

cos 60 vale 1/2 ed indica il coseno di 60 gradi, per cui sarebbe più corretto indicarlo come cos(60°) racchiudendo l'argomento tra una coppia di parentesi tonde e specificando che si tratta di un angolo.. cos(60°), così come cos(30°) e cos(45°), è uno di quei valori delle funzioni goniometriche che vanno necessariamente ricordati a memoria se si vogliono svolgere agevolmente gli esercizi.
