We may regard this divided
difference as an estimate of
at
x
i
or at
x
i+
1
or at the midpoint between
x
i
and
x
i+
1
.
b.
The Secant method
We
simply replace
by the divided difference in the Newton-Raphson formula:
.
Notice the indices:
i
+ 1,
i
,
i
– 1.
With the Secant Method
, we don’t
use a functional form for
. We do have
to carry along two values of
f
, however.
