As a start, skip the math coprocessor and use lookup tables. See these for ideas:

Awesome. That last link with the explanation from Melanie has got to be one of the best writeups I have even seen. I remember her from way back when I first started playing with PICs. It's been a while since I've broken out the box of PIC stuff but she still holds a place in my list of people to envy for her brain power.

Thanks for the links. I had seen a few of them before, but I hadn't seen Melanie' explanation. I'll sit down and try to digest all of that information tonight... and if nothing else, use the co-processor for the project until I can understand what she was trying to say in all of those formulas. I see it on the screen but may as well be reading Japanese at the moment.

Cheers,
Dave
