Math Problem Statement

Find the basis of Left Null space of the given matrix A.

A =   2 4 1 3 5 −1 0 7 2 1 3 6 2 4 8  

Solution

The matrix AA is given by:

2 & 4 & 1 & 3 & 5 \\ -1 & 0 & 7 & 2 & 1 \\ 3 & 6 & 2 & 4 & 8 \end{pmatrix}$$ The **left null space** of a matrix $$A$$ consists of all vectors $$\mathbf{v}$$ such that: $$\mathbf{v}^T A = 0$$ This means we need to find the solution to the system: $$\mathbf{v}^T A = 0 \quad \text{or equivalently} \quad A^T \mathbf{v} = 0$$ ### Steps to find the left null space: 1. Transpose the matrix $$A$$. 2. Solve the homogeneous system $$A^T \mathbf{v} = 0$$. Let's compute the left null space.The left null space of the given matrix $$A$$ is spanned by the vector: $$\mathbf{v} = \begin{pmatrix} 0.8347 \\ 0.0273 \\ -0.5500 \end{pmatrix}$$ This vector forms a basis for the left null space of matrix $$A$$.
