Khan Academy: Linear Algebra: Dimension of the Null Space or Nullity

Curated by ACT

Video reviews how to find the null space of a matrix using reduced row echelon form. Shows that the vectors of the null space are linearly independent and form a basis for the null space. Extends this to show how the nullspace can be used to determine the dimension of the null space or nullity. This video also appears in the strand Algebra: Matrices. [13:59]
