Homework Help Overview
The discussion revolves around proving that the set of solutions for the equation AX=B is not a vector space, where A is an mxn matrix and B is a non-zero mx1 matrix. Participants explore the implications of B being non-zero and the conditions required for a set to qualify as a vector space.
Discussion Character
- Conceptual clarification, Assumption checking, Mixed
Approaches and Questions Raised
- Participants question whether the solution set can be consistent if B is not in the column space of A. They discuss the necessity of the zero vector being part of the solution set and explore the implications of X=0 not solving the system. There are also inquiries about the definition of a vector space and its properties.
Discussion Status
The discussion is ongoing, with participants providing insights into the properties of vector spaces and the specific case of AX=B. Some participants have offered guidance on the conditions that must be met for a set to be a vector space, while others are still seeking clarification on these concepts.
Contextual Notes
There is a focus on the requirement that a vector space must contain a zero vector, and participants are examining the implications of B being non-zero on the closure properties of the solution set. The conversation reflects a mix of understanding and confusion regarding the definitions and properties of vector spaces.
