35:00 we arent supposed to multiply the number itself into the minor, so all the answers should be 1s and -1s, not zeros. for eg: Ca12= (1*0)-(0*0)=1 , NOT 0*((1*0)-(0*0))
Mam main last k kuchh concepts nhi samjh paaya aur na question samjh paaya... aap padha he aisi rahi h ki koi below average student ko samjh nhi aayega.... Bura mt manna but aap aise padhate h jaise sabhi student topper h 😥😥
Okay!!!! Leme first tell that I'm the only one in the entire world who has taken maths in optional as a humanities students and finally here to cover my leftover syllabus 😭😭
1:18:52 Man a silly mistake u have done is area of triangle zero krne se hi eqn of line aayegi to k sath ek 1/2 multiply hoga or eqn of line x=y aayegi 😊

I have a question . That I'd adj(A) is matrix and B is matrix than how can be Find that adj(A).B is 0.their product should be a matrix. Correct me if I am wrong.

yes matrice ka basic aana chayiye bas
Thankyou very much ma'am and all PW team for your amazing initiative towards education
Hm to school chale gye the😡😡😡😡
mam aap dunia ke best teachers ho jo hume last mee bhi padha rahe ho thank you mam and I LOVE ALAKH SIR😍😍😍✍🙏🕘🖊🖊🖍⬛🔲
THANKS MAM FOR THIS AMAZING LECTURE 🙂
00:34:29 mam your answer is wrong...of a¹³ because a¹³ minor is ( 0*0 - 0*1 ) = ( 0 - 0 ) = 0. And cofactor of a¹³ = 0
yeah dude..

Man a silly mistake u have done is area of triangle zero krne se hi eqn of line aayegi to k sath ek 1/2 multiply hoga or eqn of line x=y aayegi 😊
Nope bro 1/2∆A=0
So when you'll shift 1/2 to rhs it'll be multiplied by 0
So ultimately you'll get ∆A=0 for a straight line
Hope this helps :)

I have a question . That I'd adj(A) is matrix and B is matrix than how can be Find that adj(A).B is 0.their product should be a matrix. Correct me if I am wrong.
if it says that = 0 means the matrix is
[0 0
0 0 ] so its determinant will also be zero, hence zero matrix = 0
