Degrees of freedom? Is this statistics?
If k = 2, like you said, we have a row of all 0.
What does that tell you?
I have a small question, I am not sure about it.
I had a system of linear equations. I was asked for which values of k, the system has infinite number of solutions, with 2 degrees of freedom.
The degrees of freedom thing kind of confused me, usually I know how to approach these things.
I have eliminated the system, the attached photo contains the matrix of the system (including the vector B as last column) after I eliminated it in the Gausian way.
What do I do now ? What's with the degrees of freedom ?
if I didn't have the degrees of freedom condition I would say k=2....does it change the answer ?
