Probably a version problem.
steve:~$ perldoc -f sin
sin EXPR
sin Returns the sine of EXPR (expressed in radians). If EXPR is
omitted, returns sine of $_.
For the inverse sine operation, you may use the
"Math::Trig::asin" function, or use this relation:
sub asin { atan2($_[0], sqrt(1 - $_[0] * $_[0])) }
steve:~$ dpkg -l perl-doc
ii perl-doc 5.8.0-15 Perl documentation.
Upgrade and try again. If it persists, file a bug.
