Math 110. Linear Algebra
Department of Mathematics
University of California, Berkeley
Fall 2007
This is an introductory course on linear algebra. We will study linear
algebra from both an abstract point-of-view with vector spaces and linear
transformations playing the central roles and also a more concrete
approach emphasizing matrices and vectors in Rn.
We will discuss some applications of linear algebra.
The official prerequisite for taking this course is Math
54: Linear algebra and differential equations.
