Practice question · Sort into groups
Sort these determinant values into Invertible or Singular.
Groups: Invertible · Singular
- det = 0.0
- det = 5
- det = 0.001
- det = 0
Hints
- Only one value places a matrix in the singular category.
- Size and sign are irrelevant, only vanishing matters.
Show the answer
Invertible: det = 5, , det = 0.001
Singular: det = 0, det = 0.0
Why
Any nonzero determinant, however small, means the matrix is invertible.
