Get Constants - Maple Help

ScientificConstants

 GetConstants
 list the full names or symbols of all physical constants

 Calling Sequence GetConstants( 'names', 'derivedfrom'=Const )

Parameters

 'names' - (optional); specify that the full names be returned Const - (optional) symbol; return physical constants that are derived from Const

Description

 • The GetConstants() command returns an expression sequence containing the symbols of the physical constants in the ScientificConstants package.
 • The GetConstants( 'names' ) command returns an expression sequence containing the full names of the physical constants in the ScientificConstants package.
 • The GetConstants( 'derivedfrom'=Const ) command returns an expression sequence containing the symbols of the physical constants that are directly derived from the constant of name or symbol Const.
 • The GetConstants( 'names', 'derivedfrom'=Const ) command returns an expression sequence containing the full names of the physical constants that are directly derived from the constant of name or symbol Const.
 • The sequence of names or symbols is sorted alphabetically.
