The following page
www.interstice.com/~sdattalo/technical/theory/sinewave.html
has a nice summary of ways to calculate sine and cosine without a built-in sin() function. Personally, I would be inclined to use
method 2: just build a table with all the sines and cosines you want! (This is Teradata, after all.) You could populate it using a
Perl or C program.
If you need to be really accurate, the Taylor series (method 6) is probably your best bet, but that's a lot of work.
