The value of fe for y^Q = \K is unity for all these values of n. 



The corresponding values of the integrands of (4.2), (4.3) 

 w^ere next calculated, the expressions for them being suitable 

 for logarithmic computation. As examples of the way in 

 which the integrand varies between the limits of 70^ t'.e., o 

 and \ X, the following values are given (here to three decimal 

 places only) for the two extreme values of w : 



Integrands of Ii and I2 (c/. 4.2 and 4.3).
