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]
