Lookup tables generally are faster but you loose accuracy... To be honest I really wouldn't worry about it. Try it using Maths functions and if it needs to be faster swap to a sine look up table.
Also if you're using Blitz3D (as the forum suggests) you can use the built in 3D functions. Create pivots, position them and use entitydistance, entityyaw, pointentity etc. Depends what you're doing though.
