    Linear Algebra Question: Eigenvectors & Eignvalues

    This is my last week in Linear Algebra. I am working on our last homework assignment before the exam so I want to make sure I know what I am doing. In each part, make a conjecture about the eigenvectors and eigenvalues of the matrix A corresponding to the given transformation by considering...

    Linear Algebra Question: Determinant

    Okay. I found the determinant of this 3x3 matrix: It is b1x + a2y + a1b1 - a2b1 - b2x - a1y I simplified it: b1x - b2x + a2y - a1y - a1b1 - a2b1 = 0 I'm not sure if this will help, but I did this next. b1x - b2x + a2y - a1y + C ; c = constant a2y-a1y = C - b1x + b2x y(a2 -...

    Linear Algebra Question: Determinant

    I'm not sure if the question is asking what the graph of the determinant would look like or the matrix?

    Linear Algebra Question: Determinant

    Sorry, I forgot about it being a 3x3 matrix.

    Linear Algebra Question: Determinant

    The determinant is b1x - a2b1 a2b1 is a constant. So wait, I had that wrong. it is a straight line with a y-intercept which is some constant. How do you say that though?

    Geometry of Linear Systems: True or False?

    Okay. I decided to just choose systems to look at for a few of these problems. True 1. I found that Ax = 0 would also have infinitely many solutions. False 2. I found that Ax=0 would also be inconsistent. I'm not even sure where to begin with the others.

    Geometry of Linear Systems: True or False?

    I have taken Linear Algebra, but it has been a long time. I'm taking this course online and it is a lot harder to understand.

    Geometry of Linear Systems: True or False?

    I am taking a Linear Algebra class to finish up my master's degree in math curriculum and instruction. I have been doing okay until these questions. I need some help. True/False 1. If Ax=b has infinitely many solutions, then so does Ax=0. 2. If Ax=b is inconsistent, then Ax=0 has only...
