Linear Algebra - Introductory Problems Related to Vector Spaces

Linear Algebra



 Problems demonstrating the concepts introduced in the previous tutorial. Checking or proving something to be a sub-space, demonstrating that something is not a sub-space of something else, verifying linear independence; problems relating to dimension and basis; inverting matrices and echelon matrices.

Here are the kind of problems which have been solved in this tutorial :

  • Identifying if a set of vectors is linearly dependent.
  • Let V be a vector space of all functions from R into R and let E be the subset of even functions and let O be the subset of all odd functions. Prove that O and E are subspaces of V.
  • Showing that a given vector space is (or is not) a subspace of R3
  • Let V be the real vector space of all functions following sets of functions are subspace of f from R into R .Check whether given functions are a subspace of V.
  • Finding the dimension and basic of all points lying on a given straight line.
  • Showing that given vectors form a basis over R3
