3.2 Properties of Determinants - Video

Section 3.2 Slides

Topics covered

  • Using row operations with computing determinants
  • Combing cofactor expansion with row operation to compute determinants
  • Properties of determinants, transpose, products of matrices
  • If determinant of matrix is zero then the matrix is singular (i.e. no inverse)
  • If determinant of matrix is non-zero then matrix is nonsingular (i.e. inverse of matrix exist)
  • Several examples

Errors/Typos/Omissions in Video

  • Time mark in video: 3:53. Omission: On Example 1, I omitted the row op -2*R1 + R3 ---> R3 to get the matrix 5*[1 3 4; 0 0 2; 0 1 3]
