Trig Functions

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. Parameter is in degrees.

Sin(90) → 1

Cos(Degrees(Pi)) &rarr -1

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

plot for -90≤x≤90

Hyperbolic trig functions. The parameter is in degrees.

An xy-graph of Sin(x) vs. Cos(x) plots a circle. Analoguously, an xy-graph of SinH(x) vs. CosH(x) plots a hyperbola (on the right

Functions ArcCosH, ArcSinH, ArcTanH

these require Analytica 4.3

Inverse hyperbolid trig functions. The returned value is in degrees.
