Chapter 2:
Documenting Polynomial Zero Finding
The emphasis in this chapter is on creating a simple mathematical document about the finding of
the zeros of a polynomial. At the same time you will learn the corresponding basic techniques of
using D .

Start the new document with an appropriate headline.
Insert a text object containing the text "Finding the zeros of a polynomial."
You will look for the zeros of the polynomial

with the settings from the initialization file, i.e. with some of the
