Linear Algebra Conceptual Questions
• What are the possible sizes of solution sets for linear
systems?
• List as many things that are equivalent to a square matrix being nonsingular as you can.
• List as many things that are equivalent to a square matrix being singular as you can. (Should be basically the same as your list above except all opposites) • Give an example of a singular matrix that is NOT just the zero matrix.
• If a system has m equations and n unknowns where m < n, what are the possibilities for number of solutions to the system?
• Rephrase the question above, and your answer to it, in terms of the rank of the coefficient matrix for the system.
