from the functions
.
For a fixed initial value
and a fixed p
we define the sequence
by

Of course, as it stands, although it is clear that
converges to
to p-th order, it is not very practical.
The idea is to write the sequence recursively. Therefore there are
two problems to solve:
Table 1 contains some functions we defined in MAPLE and that we
used to find and prove initial values and iterations.
