#136063 - Don't overlook the obvious
Responding to: ???'s previous message
Some (most?) C compilers come with a library that includes floating point trig functions. Why don't you try those first to see if a) they're fast enough, and b) you have enough memory for them. If they answer to both questions is "yes", then you're done!
