Parameters

 known_functions - literal name; 'known_functions'

Description

 • The FunctionAdvisor(known_functions) command returns a list of the mathematical function's names implemented in the Maple system.

You can get a table of information for each function by specifying the function and the table keyword.

 > $\mathrm{info_arccot}≔\mathrm{FunctionAdvisor}\left(\mathrm{table},\mathrm{arccot}\right)$
 arccot belongs to the subclass "arctrig" of the class "elementary" and so, in principle, it can be related to various of the 26 functions of those classes - see FunctionAdvisor( "arctrig" ); and FunctionAdvisor( "elementary" );
