−  === Description ===
 +  
−  Linear systems, matrices, vectors and vector spaces, linear transformations, determinants, inner product spaces, eigenvalues, and eigenvectors.
 +  
−   +  
−  This course is aimed at majors in mathematics, the physical sciences, engineering, and other students interested in applications of mathematics to their disciplines. Linear algebra is used more than any other form of advanced mathematics in industry and science. A key idea is the mathematical modeling of a problem via systems of linear equations.

−  Upon completion of this course, the successful student will be able to:
 +  
−   +  
−  # Use Gaussian elimination to do all of the following: solve a linear system with reduced row echelon form, solve a linear system with row echelon form and backward substitution, find the inverse of a given matrix, and find the determinant of a given matrix.
 +  
−  # Demonstrate proficiency at matrix algebra. For matrix multiplication demonstrate understanding of the associative law, the reverse order law for inverses and transposes, and the failure of the commutative law and the cancellation law.
 +  
−  # Use Cramer's rule to solve a linear system.
 +  
−  # Use cofactors to find the inverse of a given matrix and the determinant of a given matrix.
 +  
−  # Determine whether a set with a given notion of addition and scalar multiplication is a vector space. Here, and in relevant numbers below, be familiar with both finite and infinite dimensional examples.
 +  
−  # Determine whether a given subset of a vector space is a subspace.
 +  
−  # Determine whether a given set of vectors is linearly independent, spans, or is a basis.
 +  
−  # Determine the dimension of a given vector space or of a given subspace.
 +  
−  # Find bases for the null space, row space, and column space of a given matrix, and determine its rank.
