Trigonometric Functions
Important: Analytica's Trig functions operate using degrees, not radians.
Function Radians
Radians(Degrees : atomic numeric)
Converts an angle measure expressed in degrees to the equivalent measure expressed in radians.
Function Degrees
Degrees(Radians : numeric atomic)
Converts an angle measure expressed in radians to an equivalent degree measure.
Functions Cos, Sin and Tan
Basic trig functions.
Functions ArcCos, ArcSin, ArcTan, ArcTan2
ArcCos( X : Numeric atomic) ArcSin( X : Numeric atomic) ArcTan( X : Numeric atomic) ArcTan2( Y,X : Numeric atomic )
Inverse trig functions. Results are in Degrees. The range of the results are as follows:
Function  Range (in degrees) 

ArcCos  0 to 180 
ArcSin  90 to 90 
ArcTan  90 to 90 
ArcTan2  180 to 180 
Note: ArcTan2(0,0) returns 0.
Functions CosH, SinH, TanH
Hyperbolic trig functions.
