acos

→ acos()

E menola `cos`: e tsaya palo magareng ga -1 le 1, e bo e busa sekhutlo.

acos(boleng)

acos ke cos e menotsweng, fela jaaka asin e menola sin.

E batla palo e e magareng ga -1 le 1. Ka tlwaelo matswela a magareng ga 0 le PI (e ka nna 3.14); fa seeloSaSekhutlo(DEGREES) e beilwe, a magareng ga 0 le 180.

Ela tlhoko pharologano le asin: acos ga e ke e busa palo e e kwa tlase ga 0. acos(0) ke SEPHATLO_PI, mme acos(1) ke 0.

Leina le sala jaaka le ntse — bona sin.
