A square matrix having all the elements above the leading diagonal equal to zero is known as:
Show Hint
- Null Matrix
- Zero Matrix
- Upper Triangular Matrix
- Lower Triangular Matrix
The Correct Option is D
Solution and Explanation
Step 1: Recall matrix definitions.
- Upper Triangular: all elements below the diagonal = 0
- Lower Triangular: all elements above the diagonal = 0
- Null/Zero matrix: all elements = 0
Step 2: Match with description.
All elements above diagonal = 0 → Lower Triangular
Top Questions on Matrices
- If \(A = \begin{bmatrix} 3 & 1 \\ -1 & 2 \end{bmatrix}\), then show that \(A^2 - 5A + 7I = O\). Using this, obtain \(A^{-1}\).
- If \(A = \begin{bmatrix} 1 & 3 & 3 \\ 1 & 4 & 3 \\ 1 & 3 & 4 \end{bmatrix}\), then find \(A^{-1}\).
- If \(A = \begin{bmatrix} 3 & \sqrt{3} & 2 \\ 4 & 2 & 0 \end{bmatrix}\) and \(B = \begin{bmatrix} 0 & 1/4 \\ 0 & 0 \\ 1/2 & 1/8 \end{bmatrix}\), then prove that \(|C| = 1\), where \(C = (A')' B\).
- If \( A \) and \( B \) are two matrices of order \( n \) which are invertible, then prove that \( (AB)^{-1} = B^{-1}A^{-1} \).
- For matrix \( A = \begin{bmatrix} 1 & 1 & 1 \\ 1 & 2 & -3 \\ 2 & -1 & 3 \end{bmatrix} \) show that \( A^3 - 6A^2 + 5A + 11I = 0 \) and with the help of this find \( A^{-1} \).
