Learning outcomes

After completing the course, the student
  • knows the definitions of the eigenvalues, -vectors, and -spaces of a linear mapping and square matrix, and can find these for a given mapping and matrix
  • is able to examine whether a given square matrix is ​​diagonalizable
  • is able to apply a quadratic form associated with a symmetric matrix to identify and recognize conic sections and quadratic surfaces
  • Is familiar with the definitions of symmetric linear mapping and matrix, and the importance of symmetry in finding eigenvalues and -spaces and in diagonalizing
  • is familiar with the notion of least-squares solution and knows how to compute it
  • can give examples of real vector spaces and linear mappings between them
  • knows the connection between linear mappings between finite dimensional vector spaces and matrices and can use this connection
  • can calculate how changing bases changes the vector coordinates and the matrix corresponding to the linear mapping
  • is familiar with the general definition of an inner product space and is able to investigate whether a given mapping is an inner product
  • is able to determine the orthogonality and orthonormality of a vector set by using the inner product
  • is able to use Geogebra to familiarize with geometric concepts in the course
