LOL. I had the happy advantage of learning celestial navigation, and some of 
the associated trig, a year before studying the subject in school, so the 
"slimeys" were old friends to me.

Oh, what a shame! They're great fun for this sort of thing. I write quite a 
lot of stand-alone software, but when I want to work out celestial navigation 
calculations, I almost always start with a spreadsheet. If you need a table 
of haversines for every tenth of a degree, you can assemble one in about... 
hmmm... I'll time myself... OK. Done. It took me five minutes and that 
included some time making a nice graph (I got distracted). Do you know if you 
have a spreadsheet program pre-installed on your computer? Are you on 
Windows? Mac?

Yes, there are quite a few nice books out there that spell it all out. Some 
even have *your* name on the cover. :-)
