Thank you so much for this video. I have spent all weekend trying to figure this one thing out - this is literally the only piece of media (including things online!) that I have found that actually is clear and not full of gross math jargon. My hero of the month for sure!

Great video sir but your Reduced Row Echelon form is slightly wrong, that mistake leads you to the wrong answer. With the correct form, your Rank should be three.

The basis vector of Row(A) has 5 element, How the row rank is 2? Please explain

Rank could also be the non zero rows so in A 3 rows 1 row has zeros the other 2 don’t so rank of A would be 2

I am doubt that you did the RREF wrong. (maybe my mistake). but the last number of the first line should be "-5" not 3.

so doing echolon form and doing rref u get same answer becuase they are independet?
@MathKJW
6 жыл бұрын
shahrukh khalid Echelon form usually indicates whether or not the rows and columns are independent of one another but be careful that you haven’t missed a factor. RREF will make independence obvious. The dimension of the row space will equal dimension of the column space, that is a theorem. Those dimensions also define the rank of the matrix. Note in this example that the third row is NOT independent that’s why we got all 0’s in the RREF.

Why you did reduced form form for row and column space ? I thought reduced form can only be used for nullspace. And echelon form for row space and column space. am i wrong
@MathKJW

Hakan Bozkurt Primarily because you need to determine which columns are linearly dependent. If you didn’t obtain the rref, a matrix could look like it is at full rank. Take another listen at 1:55 for some more of the subtleties.

At 1:08 I essentially repeat the definitions of the row-space and column-space with this particular matrix and starting at 1:17 I re-state the definitions in terms of the bases for these spaces. The explanation is based on those definitions.
