Abstract
In Part 1, I explained the
different techniques to
solve functional equations.
In most cases, the steps
to solve them are similar
to those in solving
algebraic equations.
However there is one
scenario where using the
algebraic method to solve
a functional equation may
lead to an incomplete
solution; i.e., only a subset
of functions that solve
the FE may be identified
and not the complete list.
This error is known as
pointwise trap. In Part II
of the twopart article
on functional equations,
we discuss the notion
of pointwise trap and
learn different ways to
overcome it.
