Linear Algebra
is one of the most beautiful subjects in the undergraduate
mathematics curriculum. It is also one of the most important in terms
of its possible applications.
Linear algebra studies the theory of abstract vector spaces and
linear transformations. Whenever one encounters a bunch of gizmos
(functions, for instance) that can be added to form new gizmos and
multiplied by scalars to form new gizmos, and for which a few
familiar rules of algebra hold, one has what's called an "abstract
vector space". The gizmos, whatever they may be, are called vectors,
or abstract vectors. A linear transformation is a special kind of
function from one abstract vector space to another. If you've ever
wished that sin(A+B) could just be sin A + sin B and sin(kA) could be
k sin A, you were wanting the sine function to be linear.
Math 206 defines "abstract vector space" and "linear transformation"
axiomatically and then deduces a very pretty story. Geometry, perhaps
unexpected, reappears -- and the abstract story that unfolds has some
very concrete, computational aspects as well. The student who takes
this course can learn computational techniques that have widespread
applications, in the natural and social sciences as well as in
industry, finance, and management.
Proof is the gold standard of mathematical discourse, and linear
algebra is especially well suited for learning to do proofs. Many
aspects of the course material are abstract, yet the logic involved
is quite direct and the proof paths are often guided by very concrete
ideas. In the course of learning some linear algebra, a student who
takes this course can learn to read and understand proofs, to judge
for herself whether a proof is valid or not, to write proofs clearly
and carefully, and to create basic proofs on her own. This emphasis
on reasoning skills is valuable for virtually any student, whether or
not she intends to major/minor in mathematics.
Math 206 is required for both the mathematics major and the
mathematics minor, and it satisfies the "proof-course" prerequisite
for both Math 302 and Math 305. Students who wish to major in
mathematics are advised to consider taking one of the following
courses soon after they complete Math 205: Math 206, Math 223, Math
225, Math
214, or Math 212.
