Hi,

Calculate, no ...

Use a retrieve table ( + linearizing ) YES ...

depends MUCH on the looked for values range.

But PBP doesn't include any "ARCCOS" function ...

Yes, you could use the ATAN function by using a cordic (http://www.picbasic.co.uk/forum/showthread.php?t=10528) include file and calculate for the equation:

You would need to do some manipulation for the math in a PIC chip though.
