I would recommend reading Jack Crenshaw's "Math toolkit for real-
time programming". The title and chapter summary make it sound
like it would be at a higher level than would be appropriate for 8 bit
microcontrollers, but how he goes about deriving methods is very
appropriate. It's also a pretty easy read for a math book.
