Thank you sir for providing such a quality content for free of cost .

[@ahmadtariq3960]

Note that for checking positive or negative definite ist thing is that the matrix has to be symmetrical it is not valid for any n×n random matrix

[@vishaljaiswal8675]

In 3:08
Sir has chhosen random matrix
Not symmetric
So for any matrix check minors for positive or negative definite..?

[@anjutundwal8391]

Matrix need not be symmetrical when we check it's definiteness, it's a random matrix.

[@RanjangamingYT7477]

1:14:25 D option not equivalent bola ha D always true hoga

[@aasthatanwar4572]

You are great sir,you never failed to amazed us with your short tricks❤❤❤❤

[@anjutundwal8391]

Nice lecture ❤. And thank you

[@spirituality-b.r.7853]

very help ful and well explained, me sare lecture dekhunga guruji

[@nidhiyadav1577]

Good evening sir,
Thank you very much sir for making this helpful lecture.
I request you sir ,aap csir net ke point of views se joh bhi important topics hai unn par lecture upload karte raheyega.

[@charitylyngdoh8912]

Thank you so much Sir 🙏

[@salma121]

Sir please do make a video on complex functions.Tq

[@mradityasharma9193]

How eigen value of A + B is equal to the sum of eigen values of A and B?

[@spirituality-b.r.7853]

very help and well explained and we can't get like thia approach in theory❤

[@Sudeeppradhan1999]

Thank you sir ❤❤❤

[@poulamighosh6271]

For negative definitie , principal minors are of alternative sign and the first principal minor must be negative sign.

[@RanjangamingYT7477]

1:53:59 d option not correct

[@madhusudanan5694]

Thank you sir.
Good explanation

[@XYZ-g5y3u]

in 14:53 if we take A=[ai^2] of order one s.t. ai not equal to zero then 0 is not eigen value of A then how we can proceed for option c & d

[@arabindapradhan2135]

Thanks for the nice video sir.....

[@hajeeranasreenqueenofscience]

Please make a video of pyq's of statistics part sir ..

[@RanjangamingYT7477]

Wow sir thank you ❤

[@rashmimalik9769]

Thanku sir aapka bahut bahut

[@shrawankumarpatel2148]

Thank you so much sir

[@positivethoughts6419]

Sir please make a video on differentiability for csir net...

[@Indigenuos]

Easy to follow ❤

[@mathematical2508]

Sir plz make this type of video for inner product

[@vishusinghofficial3506]

Thankuuu so much sir❤❤

[@professorragavan9783]

Thank you sir

[@manaspratimkalita2161]

27:09 ,B is correct,bilinear form hain

[@Zeelkumar31]

Yess it is symmetric bilinear..!!

[@Studyforcsirnetmath]

Positive definite kaise hoga?

[@dhaneshparasoya1295]

thanks sir

[@ritutiwari4687]

Thank you so much sir, your video is helpful and interesting ❤❤💯

[@ishadevi2071]

Thnku sir 😊

[@srikantakumarpatta5867]

Sir please solve previous year NBHM and TFIR for real and linear

[@paramvirsingh8158]

Sir I have a doubt in last video of quadratic form u said for negative definite first principal minor is always negative. But here u take positive for first principal minor sir pls
tell which one is correct

[@AbhishekSingh-uh3do]

same doubt

[@spirituality-b.r.7853]

no you are wrong bro, for negative definite first minor always should be positive. on basis of matrix first minor greater than zero and next should alternate sign 😊

[@Siyagupta52]

​@@spirituality-b.r.7853first should be negative

[@Siyagupta52]

​@@spirituality-b.r.7853It's D_n0 if n is even

[@Siyagupta52]

​@@spirituality-b.r.7853which book are u referring

[@priyankapoonia9080]

Dec.2014 d option is incorrect sir ?

[@othmanaljbory3649]

❤❤❤❤

[@Tanishaagarwal2]

1:18:53 pe only d option correct hoga i think its rank 3

[@Zeelkumar31]

Nope option B &D are both correct as sir written this que . Also option d is correct only entry of ther matrix a33 is 1 ..!!

[@kajalsoni6597]

If A is real symmetric matrix then it is positive definite?

[@mathssurvivor6190]

No

[@yashvardhantengauriya5708]

A is positive definite= it is symmetric

[@sasikalavijayakumar6139]

Sir dec 2018_ C also correct

[@julietkokila1170]

Option B is incorrect option C is the only right answer because the eigens values are +1/2 and -1/2 so it is not positive definite

[@abhinikki1]

Yes, I agree with you. Plz Sir clear the doubt

[@DrHarishGarg]

I will check... But if e.values are + and - then it is indefinite

[@DrHarishGarg]

I will check... But if e.values are + and - then it is indefinite

[@RanjangamingYT7477]

3:33 all eigan values are positive or negative concept wrong Sayed negative definite ka liya
All eigan value negative hota ha negative definite ka liya please correct or not please reply sir

[@yashvardhantengauriya5708]

Httt

[@RanjangamingYT7477]

Check karo ​@@yashvardhantengauriya5708

[@Studyforcsirnetmath]

Koi ye btaye ye example kaise choose krte hai 😢....sir ek bar m hi answer discard k liye option bta dete

[@DrHarishGarg]

Watch all my videos ... You will learn the approach.

[@Studyforcsirnetmath]
