In this segment we are take an example how

to find the rank of a matrix. So let’s suppose the problem statement is hey what is the rank

of this particular matrix here 3, 1, 2, 2, 0, 5, 1, 2, 3. So right here you can see that

it’s a three by three matrix so the largest sub-matrix which I’m going to order of the

sub-matrix which I’m going to get by a three by three matrix will be a three by three. So

that itself tells me that rank of (A) is going to be less than or equal to 3 so it can be

a maximum of 3 but it might be less than that so how do we find out what is the rank of

(A) if I look at the determinant of (A), because the three by three matrix and that’s the

largest sub-matrix which I can find out of that, the determinant of (A) itself is minus

23. And you can always figure out how to find the determinant of a matrix, so it’s minus

23 it’s not equal to zero. So in this case the rank of the matrix the rank of (A) is just

3. And that’s the end of this segment.

thank you sir

Very very thank u sir

not gud dont keep another video

good

couldn't understand why isnt it 2?

wtf is Det(A) ?

wtf?

not cleared

my ears are unbalanced now

like/dislike=1 XD

Thank u sir.

Poda loose. There was no steps are written. Straightly he has gone to the answer 😒

wtf

What about a 3*6 matrix…if one submatrix has det. Zero and other has det. Non zero…which case will we take?

Dislikes>likes😅😅😅

This is how you teach ….not even explained how did u get the rank ..an. Honest opinion

Sir! How did you even get to the answer? This is the question, end of this segment!😑

I have this kind of teachers in my class

rip left ear

You people are good for research maybe, but for academia please stay out of it. Give us your job we will do it much better than you.P.S. My research guide is like this.

That's the reason I am Here !

I am laughing my ass off. No Fs given, hahahaha

That is why there are more dislikes than likes for this video
