Method Detail

sinAndCos

public static void sinAndCos(double x,
                             double[] sincos)

Computes sine and cosine of an angle together. Values are returned in the array provided [angle sine, angle cosine]. This array should be of size 2. Warning: array size is not checked for performances reasons.

Parameters:

x - angle in radians

sincos - array of size 2. Array is filled is values: [angle sine, angle cosine]

sinhAndCosh

public static void sinhAndCosh(double x,
                               double[] sinhcosh)

Computes hyperbolic sine and hyperbolic cosine together. Values are returned in the array provided [hyperbolic sine, hyperbolic cosine]. This array should be of size 2. Warning: array size is not checked for performances reasons.

Parameters:

x - value

sinhcosh - array of size 2. Array is filled is values: [hyperbolic sine, hyperbolic cosine]
