Problem: Is Singular matrix [[1,1,1],[1,1,1],[1,1,1]] [ Calculator, Method and examples ]
Solution:
Your problem `->` Is Singular matrix [[1,1,1],[1,1,1],[1,1,1]]
A square matrix `A`, such that `|A| = 0`, is called a singular matrix.
| `A` | = | | `1` | `1` | `1` | | | `1` | `1` | `1` | | | `1` | `1` | `1` | |
|
| `|A|` | = | | `1` | `1` | `1` | | | `1` | `1` | `1` | | | `1` | `1` | `1` | |
|
`=1 xx (1 xx 1 - 1 xx 1) -1 xx (1 xx 1 - 1 xx 1) +1 xx (1 xx 1 - 1 xx 1)`
`=1 xx (1 -1) -1 xx (1 -1) +1 xx (1 -1)`
