Linear Algebra Question: Solving a Matrix with k=-2 and Transposition

Click For Summary

Homework Help Overview

The discussion revolves around a matrix involving a parameter k, specifically examining the case when k = -2. The matrix is presented in a row-reduced form, and there is a focus on the implications of transposing the matrix after substituting the value of k.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants are exploring the implications of substituting k = -2 into the matrix and the subsequent transposition. Questions arise regarding the need for further row reduction and the meaning of "finding Im." Clarifications are sought about the terminology and the specific operations performed on the matrix.

Discussion Status

The discussion is ongoing, with participants seeking clarification on the original question and the operations performed on the matrix. There is an exploration of different interpretations of the terms used, indicating a productive dialogue without a clear consensus yet.

Contextual Notes

There is uncertainty regarding the terminology used, particularly "finding Im," and the specific actions taken with the matrix after substituting k. The implications of the row reduction process and the effects of transposition are also under examination.

i got this matrix
1 1 k
0 1-k k-1
0 0 (k-1)(k+2)

for k=-2
1 1 -2
0 -1 -3
0 0 0


the k matrix is row reduced
so after i put k=-2 and transposed it.
i get no all 0 lines
so i need to do row reduction again??

What's the actual question?
 
what is the general way of finding Im
 
What does that mean--"finding Im"?

Going back to your first post, you said you "put k=-2 and transposed it." What does "it" refer to? The matrix? Or do you mean that you interchanged two rows?
