Again, using the results for Part 1, and also (9.06), (9.07), and (9.19), we see that
Then substituting in (9.17) by means of (9.19) and (9.20) we arrive at
compare (9.18). Key inequalities are
Substituting these results in the bound
for ^Y,,(l-d,xO(H), we find that this variation is O(U-~) , O ( ~ - ~ l n u ) , or o(u-~/"), according as a < 1, a = 1, or a > 1.
