Detailed Description

Toolbox of Trigonometry routines useful for spacecraft operations.

Typedefs
typedef double	O_SESSAME::Angle
	Representation of an angle in radians. Currently the angle representation is assumed to be radians, and can be used in any of the other Trigonometry functions to convert to Degrees or Degrees-Minutes-Seconds. In the future, the Angle should be a class that is unit independent and include the appropriate conversion functions.
Functions
double	O_SESSAME::DMS2Deg (const double &_Degrees, const double &_Minutes, const double &_Seconds)
	Converts an angle from Degrees, Minutes, Seconds (^o,','') to a single quantity in degrees and fractions of a degree.
void	O_SESSAME::Deg2DMS (const double &_Angle, double &Degrees, double &Minutes, double &Seconds)
	Converts an angle from a single quantity in degrees and fractions of a degree to Degrees, Minutes, Seconds (^o,','').
Angle	O_SESSAME::DMS2Rad (const double &_Degrees, const double &_Minutes, const double &_Seconds)
	Converts an angle from Degrees, Minutes, Seconds (^o,','') to radians.
Angle	O_SESSAME::Deg2Rad (const Angle &_Degrees)
	Converts an angle from Degrees to radians.
void	O_SESSAME::Rad2DMS (const Angle &_Radians, double &Degrees, double &Minutes, double &Seconds)
	Converts an angle from radians to degrees, minutes, second format.
Angle	O_SESSAME::Rad2Deg (const Angle &_Radians)
	Converts an angle from radians to degrees.
Angle	O_SESSAME::atanh (const double &_z)
