It appears in the calculation of the integral of sqrt(1+s^2).
Also, notice that integrate(1/sqrt(1+s^2),s)=asinh(s)
One could also obtain the result using log functions, since asinh(s) =

Very interesting; thanks for the reference.

Well, I've never tried cricket, but baseball is definitely one of my
