@1:49 Orrrrr u guys could just interchange the left diagnol I.e. interchange places of 3 with 2 and then change signs of the right diagonal I.e write -5 and -1 instead of 5 and 1🤗 (but this shortcut method only works for 2×2 matrix)
Isn't it ironic that a channel called Don't Memorise literally only shows you calculations to be memorized while giving you zero intuition of what you're actually doing.
You don't need all this for 2x2, for example... _ _ | a b | | c d | _ _ just exchange ( a ) and ( d ), and give minus to both of ( b ) and ( c ). _ _ | d - b | | - c a | _ _

It's the underlying concept but in school we were taught that the diagonal 2 3 will have place change and the diagonal 5 1 will have sign change. With that set we would get the exact same result within seconds. But Thanks for this video. It seemed hard for me through this method though.

The cofactor of 3 had been done wrong it Should be 1

Check urself
Now its a type of video one can rely upon just before his/her math exam....thank you!!!
Why wait for exams? 😜 You can rely on our videos whenever you're studying 😉

Yeah sure buddy I have my exams tomorrow
Yeah bro😁
Exactly 😂
Wow! Best video on adjoint matrices on youtube by far! Understood in 3 minutes what I couldn't get in a 1:20 Hr lecture!
HAHAHAHAHA Same pinch
Which idiot was teaching this in 1hour 20mins

Yah so true, just like chemistry has exceptions,this channel too got some exceptions😂
Yes it is ironic
So clear and concise. Terrific presentation. Love these videos.
Ma Shaa Allah. You explained it in a very short time and in an easy way. Thank you so much!
Yeah mashallah sister explained very well indeed
when dont memorise turns to be just memorise
You don't need all this for 2x2, for example...
_ _
| a b |
| c d |
_ _
just exchange ( a ) and ( d ), and give minus to both of ( b ) and ( c ).
_ _
| d - b |
| - c a |
_ _
This will be 2 much memorizing
I loved this technique. Textbooks are so screwed up here in my country.

Short and better than any other video
swap the entries on the main diagonal and reverse the sign on the entries on the other diagonal got it
