Outline of the topics covered in class
References to the paragraphs of the textbook are given in
parentheses, when possible.

Lecture 1  September 18, 2017: recalls of selected topics
from chapters 1 to 5 of the textbook. It is important to
remember that all the topics contained in these chapters are
considered known.

Approaching the course.

Informations about the software packages that can help
during the course, in particular Wolfram Alpha and
Geogebra. As far as Geogebra is concerned the software
can be used directly on line in a browser's window
or downloaded and installed to your personal computer.
There is also a version suitable for use on portable
media without leaving setting files on the host
computer: see the web site geogebra.org.
