Exercise Solution 9.7
First, we construct 
from 
by setting 
= 
and interpolating a function of form [9.62] between 
, 
and 
to obtain 
, 
, … , 
. The interpolation is performed as described in Section 2.4.3. See spreadsheet. Interpolation function [9.62] becomes
[s1]
from which we obtain
[s2]
Substituting [9.64] and [s2] into [9.63] yields
[s3]
