acos
Returns the arccosinethe inverse function of the cosineof a given number. The returned angle is given
in radians within the range 0 to PI.
acos(Number)Syntax:
Arguments:
Number is the cosine of the angle you want and must be between-1 and 1.
Examples:
acos(0.5) returns 1.0472 (PI/3 radians).
degrees(acos(0.5)) returns 60.
asin
Returns the arcsinethe inverse function of the sineof a given number. The returned angle is given in
radians within the range -PI/2 to PI/2.
asin(Number)Syntax:
Arguments:
Number is the sine of the angle you want and must be between-1 and 1.
Examples:
asin(0.5) returns 0.5236 (PI/6 radians).
degrees(asin(0.5)) returns 30.
atan
Returns the arctangentthe inverse function of the tangent of a given number. The returned angle is
given in radians within the range -PI/2 to PI/2.
atan(Number)Syntax:
Arguments:
Number is the tangent of the angle you want.
Examples:
atan(1) returns 0.7854 (PI/4 radians).
