This is so useful, I wish I didn't have to struggle so much with regular substitution method for solving systems of equations. I know it's essentially doing the same thing, but it's just clearer for me to visualize the problem like this.
Let xy/2 uxx - 4(x+y+z) uxy + xy/2 uyy =0 . In which region should y lie so that the pde Hyperbolic: Option a) y> max (-1, -(1+x/1-x)) Option b) -(1+x/1-x))-1 Option d) y=x+1 and x belongs to [-7/4,11/4] Sir please tell how to solve it

5:26 but the last row doesn't have all zeros. How could it satisfy echelon form
It's not compulsory. IF is the keyword here. IF there is a zero row, it should be the last one.
was just about making the same comment. 😄
But in 2:04 the wrong way of REF we see the last row having a non zero element. Care to explain?
@@b.harishraghavan887 Because the non-zero entries being to the right, not that it ends with 2.
Thank you, I had difficulty in identifying it.
Thank you, this was helpful
Really helpful🎉
isnt the lead/pivot suppossed to be 1?
That makes it reduced row-echelon form
Depends on some textbooks
I was about to write the same comment
@@noelmekonnen4521 i think in reduced row echelon it’s one
okie tnx
Nice one ☝️
Amazing video
good shit mate👍. thanks.
