Correction of Laplace equation

[From Bill Powers (2006.12.29.0930 MST)]

I said (2006.12.23) that

    -dk(k - jw)
o = -------------
      k^2 + w^2

The cosine of the phase angle of o relative to d is -d(k^2)/(w^2 + k^2)

If I'd done it right, the expression would have been

cos(phase angle) = k/SQRT(w^2 + k^2)

I'm pretty rusty at this sort of thing.
