Hello Mr. Shrenik Jain, this is my humble request to you to make videos on GATE 2020 syllabus based on some tricky rules...your videos are quite fruitful for us...
PI 2008 - The determinant of an Orthogonal matrix is 1 or -1 but the reverse may not be true. I mean if the determinant of any matrix is 1 or -1 then it is not necessary that it is an Orthogonal matrix so the last trick may lead to the wrong answer. Apart from this other tricks are good :)
for the question from EC2009(13:50) use property of sum of diagonal value = sum of eigen value. AND for last question their is another simple trick i.e. A.A^-1 = I just check the first element to be 1
Very useful video...I loved it.... Keep making this kinda videos and encourage and support us sir..... Verryyyyyy useful and nice video..❤️❤️😍😍👍👍👍👍👍👍👍 good job
Last question can also be solved by.. (33:54) Product of A and A inverse is Identity matrix. So just take first row of given matrix and multiply it with first column of every option It should give answer 1. Btw nice video. Thanks
1 Question me ek trick mai batata hoon 1 equation ke coefficient ko man lo a1,b1,c1 r 2 equation ke a2,b2,c2 agar a1/a2 is not equal to b1/b2 hai toh unique solution agar a1/a2=b1/b2=c1/c2 ho gaya toh infinite solution..
Any upper or down triangle elements are zero then the diagonal elements are the eigenvalues. You can directly write the diagonal elements as eigenvalues
I have a dought We have another property that is Sum of eigen value = sum of leading diagonal element From this property we get ans -1 So hw it is possible that two property intersect each other
Sir I am civil engineering student . I'm preparing gate exam and other related engineering exam . I want your short notes .Please tell me how many cost of maths note ... Sir
9:35 Given matrix is not an orthogonal matrix since they mentioned it was orthogonal, the answer is C but the given matrix was not an orthogonal matrix. the determinant of the given matrix is 8 which means it's not an orthogonal matrix
First question matrix me le hi jaana kyu? 😂😂🤣🤣 X1=X2 And given that X1-X2=0 Just put in 3rd gives X3 = 1 Put in first gives 2X1+1=3 Which gives X1=1 Now x1=x2=1 and X3 is also 1.🤣 Which is indeed a unique solution. 🤣
2nd last question mai... sum of diagonal = sum of egien values vali property fail ho rhe hai...0+0=0 aayega..par egien values ka sum kiya toh 0 nhi aa rha... Plz acknowledge
