Any Mathematicians Onsite with a spare 5 minutes?

tachyon has asked for the wisdom of the Perl Monks concerning the following question:

At How can I get sine, cosine, and tangent to return values in degrees? a fellow monk stefan_k wnated a module Math::Trig::Degree which I have just written and uploaded to CPAN. It will handle degrees or radians.

I wrote a fairly extensive test suite. The output of one of the test scripts is shown below. It has been a long time since I did trig so I would greatly appreciate a mathematician having a look over the output. In particular the edge cases and results for -ve angles with some of the less common functions.

The test script tests that produced this output are all in the form:

for ( $i = 0; $i<=360; $i+=15 ) {
    printf "func %3d %5f\tinverted %.1f\n", $i, func($i), afunc( func(
+$i) ), "\n";
}

Seems all OK to me. sin is invertible in -90..90, cos in 0..180, tan in 0..180. sec=1/con, cosec=1/sin, cot=1/tan. -- dakkar - Mobilis in mobile	[reply]

Thanks for having a look. I have subclassed so the base class will handle any units you like now. cheers tachyon s&&rsenoyhcatreve&&&s&n.+t&"$'$`$\"$\&"&ee&&y&srve&&d&&print	[reply]
