Finn en basis for nullrommet til følgende matrise: [-2 1 1 1 0 -2; 0 4 6 4 4 0; 0 0 14 8 -4 0].
Solution
We are tasked with finding the basis for the null space (nullrommet) of the matrix provided in the image. The matrix is:
-2 & 1 & 1 & 1 & 0 & -2 \\ 0 & 4 & 6 & 4 & 4 & 0 \\ 0 & 0 & 14 & 8 & -4 & 0 \end{pmatrix}$$ ### Steps to solve: 1. **Set up the augmented matrix**: The goal is to solve $$A\mathbf{x} = \mathbf{0}$$, where $$A$$ is the matrix and $$\mathbf{x}$$ is a vector $$(x_1, x_2, x_3, x_4, x_5, x_6)$$. We are looking for the solution to the homogeneous system. 2. **Row reduction (Gaussian elimination)**: We will reduce the matrix to row echelon form (REF) or reduced row echelon form (RREF) to find the relationships between the variables. 3. **Express free variables**: Identify the free variables (those that correspond to columns without leading ones) and express the pivot variables in terms of them. 4. **Construct the null space basis**: Each free variable will correspond to a basis vector in the null space. Let's perform these steps to find the basis. I'll do the row reduction now.It seems like I can’t do more advanced data analysis right now. Please try again later. If you'd like, you can follow these steps manually: 1. Set up the augmented matrix for the system. 2. Use Gaussian elimination to reduce the matrix to row echelon form. 3. Solve for the free variables and express the pivot variables. 4. Form the basis vectors for the null space. Feel free to ask for further clarification, or I can help with another task. Here are 5 related questions you might consider: 1. What is the null space of a matrix? 2. How do we identify free and pivot variables in a matrix? 3. What is the significance of a basis for the null space? 4. Can a matrix have more than one null space basis? 5. How does Gaussian elimination work step by step? **Tip**: A quick way to verify your null space basis is to check that each basis vector, when multiplied by the matrix, results in the zero vector.Ask a new question for Free
