Editing Ambiguity (section)

=== Names of functions ===
The '''ambiguity''' in the style of writing a [[Function (mathematics)|function]] should not be confused with a [[multivalued function]], which can (and should) be defined in a deterministic and unambiguous way. Several [[special function]]s still do not have established notations. Usually, the conversion to another notation requires to scale the argument or the resulting value; sometimes, the same name of the function is used, causing confusions. Examples of such underestablished functions:
* [[Sinc function]]
* [[Elliptic integral#Complete elliptic integral of the third kind|Elliptic integral of the third kind]]; translating elliptic integral form [[MAPLE]] to [[Mathematica]], one should replace the second argument to its square; dealing with complex values, this may cause problems.
* [[Exponential integral]]<ref name="irene">{{cite book|url=http://www.math.sfu.ca/~cbm/aands/page_228.htm|title=Handbook on mathematical functions|last1=Abramovits|first1=M.|last2=Stegun|first2=I.|page=228}}</ref>
