MATH1048 Linear Algebra I
Linear maps on vector spaces are the basis for a large area of mathematics, in particular linear equations and linear differential equations, which form the basic language of the physical sciences. This module restricts itself to the vector space R^n to build an intuitive understanding of the concepts of linear algebra and tools for calculations. We begin with the geometry of lines and planes in R^3 and R^n looking at the intuitive concept of vectors on the one hand, and with systems of linear equations on the other. This leads us to matrix algebra, and in particular the inversion of matrices.
Aims and Objectives
This module restricts itself to the vector space R^n to build an intuitive understanding of the concepts of linear algebra and tools for calculations.
Having successfully completed this module you will be able to:
- Solve systems of linear equations
- Calculate the determinants, and invert matrices
- Apply linear algebra methods to geometric problems in R^3 and R^n.
• Complex arithmetic • Vectors in R^n: examples from R³, equations of lines and planes in R³. • Systems of linear equations, Gaussian elimination. • Matrix algebra: nxm matrices, sums, products, transpose, inverse of an nxn matrix, matrix equations. • Determinants, cofactor definition of the inverse, proof that detA?O if and only if A invertible. • Properties of R^n, subspaces of R^n, span, null space and column space of a matrix. • Linear independence of vectors in R^n. • Scalar product and geometrical applications. • Vector product and applications in R³. • Linear transformations in R^n, examples in R² and R³. • Eigenvalues and eigenvectors. Throughout the module some theorems will be proved.
