The FunctionAdvisor(calling_sequence, math_function) returns the calling sequence of the function.

Note that syntax and form are synonyms of calling_sequence. For more information, see FunctionAdvisor/synonyms .

If the math_function accepts more than one calling sequence, for example, Ei , by default, the FunctionAdvisor(calling_sequence, math_function) command returns the calling sequence with the most arguments. To obtain all the calling sequences for the math_function, specify the optional argument 'all'.
