Sir please add English subtitles because we South Indian students will also understand clearly
Amazing video sir , alpha* = 1/2 and beta* = -37/16 ( by completing the square method ) , so the answer comes out to be -29/16. Thankyou so much sir for such an amazing shortcut
Sir shortcuts ki v ek playlist create karde plzzz
There are lots of assumption needed for the trick to be valid:
1) u need to always check if the given nth degree eqn for the nxn matrix is the characteristic eqn of the matrix or not, then only we can say that the product of roots is the product of eigenvalues (det(A)) and and the sum is trace (sum of eigenvalues)
2) you just cannot blindly assume that the given equation will always be a characteristic equation (in most of the jee questions it is), there's a theorem that if the eigenvalues are distinct for the given matrix, then the characteristic polynomial is the least polynomial satisfied by the matrix, so any other polynomial of same degree will be just a constant multiple of that
Basically, every matrix satisfies its characteristic eqn, but if a matrix is satisfying some eqn, it need not be the characteristic eqn
The questions do satisfy these conditions, that is why the trick works, JEE advanced always gives valid questions, sadly the theory taught to you guys isn't valid enough.
In the jee advanced question if u check the characteristics eqn of M, which is quadratic, the disciminant of it is never 0 (u can check), that is why the eigenvalues are always distinct, that is why the given polynomial can be taken as some scalar multiple of the characteristic polynomial, that is why the sum of roots will be the sum of eigenvalues (that is = trace)
sir subscription chahiye plus ka uske price 9999 ho gye sir please 5499 krvado ya btado kitne din baad price drop hoga
Bhai use code = NEXUSAK
Uske baad 5499 ho jayega 😊
Bhai use coupon code = NEXUSAK
Bro, Mohit Tyagi Lelo sbse best hai

Haa brother Mohit sir ka le le ....😊
Amazing video sir , alpha* = 1/2 and beta* = -37/16 ( by completing the square method ) , so the answer comes out to be -29/16. Thankyou so much sir for such an amazing shortcut ❤❤❤🔥
Sir great video answer to hw question is alpha=1/2 and beta*=-37/16....used conpleting square method so answer tovalpha*+beta* is -29/16
Thank you sir please provide more videos ❤❤❤
Bro can you elaborate your method ? I got the same answer but want to see your method .
Sir, α = 1/2
β = -37/16
And so ans -29/16 hojayega....Thanks Sir!!!🙂🔥✨
Loved the video sir and make these type of tricks more ❤❤❤
Do let us know in the comments which topic you need in next video.
@@JEEnexus Sir please make a strategy video on bitsat if possible as it is in next 20 days 🙏
@@JEEnexusapplication of derivatives please
1:20 how alpha = -7
and beeta = 12 plzz anyone explain 😢
Sir is the correct option (D) -29/16
And B(beta) = - 37/16
Sir, how to do cengage for Jee Advance, I am currently in 12th.
galath hai bhai
Sir ji characteris eqn se 15 sec me nikal jaega 😅😅😅
Beta = negative of a quantity which is always positive
This implies that quantity must be at its maximum for beta to be the most negative and hence attai its min
-Beta=(sin²2x/4+1/2)²+7/4
Max of rhs is at sin²2x=1
So beta=-37/16
Short cut for itf❤
Mah toh practice karna kah baad bhi matrices kah formulas bhul jata huin 😢
H.W problem
the correct option is B
home work
the correct option is option B
im the first to answer!!!!
😮😮😮😮😮😮😮 sir woow
I will do 20 plus from 5 june
Up wale attendance laga k jaye 😊
me solving tb grade 12 matrices-easy ,me solving jee matrices my mind is 2000percent twiated i wish they will teach this at school and jee should be mixed with t/b
First❤❤
I am first sir and loved the video
Sir great video answer to hw question is alpha=1/2 and beta*=-37/16....used conpleting square method so answer tovalpha*+beta* is -29/16
Thank you sir please provide more videos ❤❤❤
Beta = - 37/16 😊
Love you bhai❤😊
Hey sir please please ek graph transformation pe advanced ke lia video bnai please thodi lambi video bnaiyaga lagbhag 3 ghante ka please 🥺🥺🥺🥺🥺🥺🥺
Option D sahi hai
Hey sir please please ek graph transformation pe advanced ke lia video bnai please thodi lambi video bnaiyaga lagbhag 3 ghante ka please
Thank you sir for the short cut alpha is 1/2 and beta is -37/16 the final answer is -29/16
Being studying maths offline I still do math by learning from arvind sir .
Thank you for these tricks Sir!
This is basically Formation Characteristics equation of matrix ❤ Nice concept

sir nimbus reloaded batch ma syllabus starting sa karaya jaya ga kya ya fir recorded ho ga starting ka syllabus
❤
maja aa gaya👍
thank you so much for what youve done so far sir, really helpful
Love you shera. God bless you.
