Bug#731506: Math::Trig many arguments not mentioned

[jidanni at jidanni.org]

Package: perl-doc
Version: 5.18.1-4
Severity: wishlist
File: /usr/share/man/man3/Math::Trig.3perl.gz

Many of the functions on this page are missing their arguments.
Being that one can get away with giving many of them any number of
arguments, please at least mention something like perldoc -f sin does.
Don't just assume they are "well known".
