After
having finished your book today, I agree completely with the
very favorable reviews that I saw on the internet. It was
an enlightening experience to brush up my old university math
with this book. The 'sketchy' way of explaining things sure
worked for me.

First
of all, many thanks to you and Professor Hansford for creating
"Practical Linear Algebra, A Geometry Toolbox," it's done
a world of wonder for me, as I need to review my linear algebra
to prepare for studying computer graphics. I really can't
thank you enough.

Your
book "Pratical Linear Algebra, a geometry toolbook " is great.
I write software for image analysis of medical images where
in several occasions I have to deal with eigen things and
similar . I have been using your book as a valuable reference
to refresh and understand these concepts that I studied when
I was a student.

I picked
up this book with the thought, ’oh, another linear algebra
text.’ I was pleasantly surprised, upon examination, that
it is not just another one. The standard linear algebra material
is presented with good motivating stories, illustrations and
examples.

I just
purchased your book, "Practical linear algebra", a few days
ago. I found it in Barns and Nobles last week, and I immediately
fell in love with it. I love the nice illustrations and diagrams
which are very helpful in promoting intuitive understanding
of every concept. I am a clinician investigator at the National
Institutes of Health who is conducting MRI research of the
heart. My main interest is finite deformation of the heart
muscle structures, however, since I do not have engineering
background, I have been looking for a nice textbook on linear
algebra.

I am
taking a Linear Algebra class  geez, what a frustrating
experience. A paedagogical disaster. We are all nonmath students
 but no applications, no substantive interpretations of
any concept. And then, panicking for finals, I went to the
Math library, found your book, and was delighted. I was awake
last night til 4am, reading it just for pleasure. keep up
the good work!

Teaching
computer graphics and mathematics in the study program Digital
Media at Bremen, Germany, I have found "Practical Linear Algebra"
to be precisely the kind of book I've long been looking for.
It covers all topics that are vital for computer graphics,
even gives lots of applications in that field including for
instance PostScript, and does so in a very practical but nonetheless
rigorous manner. I find many elements of my own teaching in
this book, including the handmade style of drawings (rendering
them more "handson"), using a geometric shape to illustrate
the action of a 2x2 matrix, and deriving the determinant from
the computation of areas and volumes instead of plainly presenting
a formula. I have recommended this book strongly to all students
in my firstyear courses and will continue to do so.

I looked
at the Practical Linear Algegra book and I was impressed with
the applications, especially those related to computer graphics.
The topics are organized in a slightly nontraditional way,
so the book does not coordinate with our current course outline
as easily as some other books do. However, I think some faculty
will be interested in using the book because the geometric
descriptions and applications are very nice.

Is
linear algebra a tool that is capable of solving a myriad
of problems or an example of mathematical structures and reasoning?
The answer, of course, is both. In this book, Farin and Hansford
certainly take the first viewpoint. Common theoremproof presentation
has been replaced by motivation, example, or graphics. Their
goal is aimed at the freshman/sophomore level and is quite
appropriate for students in engineering and computer graphics
as well as in mathematics. It is well written and the examples
are carefully chosen to motivate or exemplify the topic at
hand. As a consequence, it is significantly different from
a traditional work in the area. For example, "eigen things"
(their term) are introduced in the plane and used to diagonalize
a symmetric matrices, but the general problem of diagonalizing
a matrix is omitted. There is no mention of similar matrices.
It appears to be a very good book, if the goal is introduction
to applicaiton, but perhaps not for introduction to mathematical
proofs. Summing Up: Recommended. Lowerdivision undergraduates;
twoyear technical program students.

We have
been quite appreciative of the reviews and feedback from readers
of the first edition of this text, The Geometry Toolbox.
Reviews are included below. 
Written
in a deceptively easytoread style, ... this textbook provides
a solid foundation in the mathematics needed for graphics
and modeling. ....
The clarity of the style and the geometric nature of each
explanation by themselves makes this text an important reference.

the best in geometry.

I found your book at the SU math library. Is excellent. Part
of my job involves contact geometry and I have found your
book to be helpful. I like the fact that it is done in postscript.
Some of the best looking books ever are done in postscript.
