ACOS Function

Syntax

Arguments

radians

A number between - p and + p.

Description

Returns the arc cosine of an angle expressed in radians.

Discussion

ACOS() returns the arc cosine of a radian angle. The radian angle must be expressed in radians. For angles measured in degrees, use acos( dtor(degree_angle) ).

Example

dim pi as N
dim angle as N
pi = 3.14159
angle = 45
acos(0) -> 1.57
acos(1) -> 0
acos(-1) -> 3.14
acos(pi) -> 0
acos( dtor(angle) ) -> 0.667457
