$MaxMachineNumber is the largest machine-precision number that can be used on a particular computer system.
The basic idea behind the "StiffnessSwitching" method is to provide an automatic means of switching between a nonstiff and a stiff solver. The "StiffnessTest" and ...
JacobianMatrix[pt] gives the Jacobian matrix of the transformation from the default coordinate system to the Cartesian coordinate system at the point pt. JacobianMatrix[pt, ...
ConfigurationPath is a global option that specifies which directories are searched for systemwide configuration information.
FileNameDialogSettings -> {opt -> val} is a global option that specifies settings for the Insert File Path dialog box.
PreferencesPath is a global option that specifies which directories are searched for user-specific settings when Mathematica is started.
