Eigen values = 2, 3, 5, 7
Characteristic polynomial = (x-2)(x-3)(x-5)(x-7)
Thank you so much GP sir 🙏

[jaideepmot]

Eigen values of matrix A are 2, 7, 3, 5 and the characteristic polynomial of A is
And I solve this problem within 10 seconds by using GPSIR's trick.

[indhui]

Eigen values2, 7, 3, 5 characteristic polynomials (x-2)(x-7)(x-3)(x-5)

[anupamsamanta]

(x-2)(x-7)(x-3)(x-5)=0 is tha characteristics euuation
Eigen values are 2, 3, 5, 7
Time taken 5 sec
Nice tric sir 🙏🙏🙏

[kimberlysecretario]

I DON'T KNOW HOW TO THANK YOU SIR! YOUR METHOD SAVES TIME AND INCREDIBLE!!!!

[deshijmc]

thanks for sir distribution of knowledge

[Rajakgate]

The trick work as all matrices can be reduced to upper traingular 3*3 matrices whose Eigen values are diagonal elements and CE is just product of Factors of its eigenvalues.

[chandankumargupta]

(X-7).(X-2).(X-3).(X-5)=0 is the characteristics equation And characteristics Or eigen values are 7, 2, 3, 5.

[adititiwari]

Characteristic polynomial of A is (x-7)(x-2)(x-5)(x-3) and eigen balurs if A is 7, 5, 3, 2 and thank u so much sir for this video 🙏🙏🙏

[dipikayadav]

Characteristics polynomial of A is (x-7), (x-2), (x-5), (x-3) and eigen values of A is 7, 2, 5, 3 🙏🙏🙏

How to calculate eigenvector of 5*5 matrix in which all elements are non- zero

[aanchal]

Eigen values- 2, 3, 5, 7
Characteristic polynomial=(x-2) (x-3) (x-5) (x-7)
😇😇😇😇

Sir, Please Complete Lecture For GATE 2022.

[SurajKrmishra]

Eigen values are :-2, 5, 3, 7
And char polynomial is

[mamtakumari]

The eigen value of A are 2, 3, 7, 5 and the characteristics equation is (x-2) (x-7) (x-3) (x-5)
Very easily solved these question

[elinanikolopoulou]

Out of everything he said, the only words i understood were "2x2 matrix" and "eigenvalues", but i understood his trick through the slides

[chandankumargupta]

Sir make a video on Upper And Lower block matrices

[vijaykumarkewat]

Very helpful video sir thankyou so much

[studyvibesclasses]

Characteristics equation (x-2)(x-7)(x-3)(x-5)

[kunjdewangan]

👌👌👌..thank you so much sir jii 🙏🙏...Eigen value are 2, 7, 5, 3 nd characteristic equation is (x-2)(x-7)(x-5)(x-3).
