ASN
PURPOSE: Returns the angle value for which sine (angle value) = argument.
FORMAT:
ASN (argument)
Numeric expression
The parenthesis enclosing the argument can be omitted when the argument is a
numeric value or variable.
EXAMPLE: ASN (0.1)
PARAMETERS: argument must be within the [-1 , +1] range
EXPLANATION:
1. The unit of the returned value is specified using the ANGLE function.
2. The returned value is in the [0 , 180°] or [0 , π Radians ] range.
SEE: ANGLE, COS
ATN
PURPOSE: Returns the angle value for which tangent (angle value) = argument.
FORMAT: double atan(x) double x;
ATN (argument)
Numeric expression
The parenthesis enclosing the argument can be omitted when the argument is a
numeric value or variable.
PARAMETERS: argument must be within the [-1x10
EXPLANATION:
1. The unit of the returned value is specified using the ANGLE function.
2. The returned value is in the [-90° , 90°] or [ -π/2 , π/2 Radians ] range.
SEE: ANGLE, TAN
COS
PURPOSE: Returns the value of the cosine of the argument.
FORMAT:
COS (argument)
Numeric expression
The parenthesis enclosing the argument can be omitted when the argument is a
numeric value or variable.
EXAMPLE: COS (30)
PARAMETERS: argument: numeric expression (angle).
-1440° < argument < 1440°
-8π Radians < argument < 8π Radians
-1600 Grads < argument < 1600 Grads
EXPLANATION:
1. The unit of the argument is specified using the ANGLE function.
2. The returned value is in the [-1 , 1] range.
