You can use either a cosine or a square root curve.

I tend to prefer cosine for stereo panning and crossfading and use square root curves for 4/6/8 channel circular panning, but ymmv

You can use this example as a starting point:

thanks for all the help. i hope you don't mind if i pick your brains about this a little more?

so an i right thinking that the two of them are approximations of a natural log curve? is one better or 'truer' than the other?
