Basically if we can't solve for a certain variable, then we assume there is an infinite number of solutions to that variable. We can then substitute a generic dummy variable instead.

The beginning of the video is supposed to show the reduced echelon form, the echelon form doesn't require the leading entries to be 1, they can be any non-zero value.

The matrix is in an augmented form. The last column is the solution of the equations , therefore doesn't have any variables corresponding to it

If the pivot is 1, wouldn't it be called the reduced [row] echelon form?
@iRobotsGamer
3 жыл бұрын
It's reduced row echelon form if the pivot is a 1 and is the only non-zero entry in the column. So 0s all above and below the pivot

I'm confused about the last example matrix. On the slides, it says if p (num of equation) is smaller than the q (num of unknowns), we would have q-p free variables. Last example, we have p=4, q=5, but 2 free variables. What happened?
@ajeesha9467
3 жыл бұрын
There are only 3 equations not 4 ( since last row is all zeros) Hence 5-3=2 free variables
@amberjha5974

the 4th system is just zeroes, we can safely discard it. When we say q-p rule, we mean that that each equation has the leading column with a non-zero value.
@sebastianbejaoui9490 Жыл бұрын
The rule for determining free variables doesn't make sense. A 3x3 matrix can still have a free variable.
@chrisbeharry11652 жыл бұрын
For the Basic and Free Variables slide with "Consider a system of equations written as a matrix in row echelon form". You have your matrix in reduced *row* echelon form not row echelon form. Shit had me doubting my elementary row operations for a second
