Rank of a Matrix - New Method 

Thank you so much😊

Sir , actually both examples requires editing. But sir , still the concept of rank is totally clear to me. You are really doing good 🙂 Every concept of yours is crystal clear to me. Thanks a lot for such nice videos.

Lecture 7 done !

Sir , also in example 2 ( step 2): d²² should be 2 instead of -2. d³² should be -8 instead of -4. d⁴² should be -7 instead of 1. Hence , entire column 1 requires editing.

I was so confused about these question and i research alot to find easy method to solve the question and finally i saw this vedio and this vedio release my tension thankuu soo much sir✨✨

sir in example 1 , see step 2 (step in which you have calculated the 2×2 determinant) d²⁴ should be -26 instead of -2. d³³ should be 8 instead of 5.

Example ka second step pa mistake ha -8 0 ho ga - 8 1 ho ga

Aur example 2 me bhi

sir multiplication wrong h

Example 1 me mistake h
