+madhusree basak thanks for the appreciation. I have solved one requested question separately on hermitian. That will serve as practice question for you.
trigonometric and exponential generally asked for eigen value type questions... I didn't find for hermitian in csir net exam, if you have then do let me know I'll solve that
Sir when will you make a video on secular determinant ? There was a question in gate on secular determinant of Allyl radical . how to solve such questions ?
all operators in quantum mechanics must be hermitian. so kinetic energy operator is also hermitian operator, but i can not solved....sir please help me to solve it...
Sir apki video bhut din se nhi aa rhi ha ...please quantum complete kerwa dijiye...specially variation theorem and perturbation theorem jitne v type ke questions banta ha please sir.
For any operator A and it's adjoint A+, the incorrect statement is. 1)AA+is harmition 2)AA+ +A+A is harmition 3)A+A+is harmition 4)A-A+ is harmition how to solve
Sir couldn't you make at least 2 videos daily if possible.. Sir your videos are really helpful for us.. Sir also cover physical spectroscopy and thermodynamics as soon as possible..
HELLO SIR! PLEASE SOLVE THESE CSIR QNS QN-1 A constant of motion is defined by the equation: (a) [H, A] = 0 (b) =0 (c) A = f(H) (d) † A A QN-2 If A and B are non-commuting hermitian operators, all eigenvalues of the operator given by the commutator [A, B] are (a) complex (b) real (c) imaginary (d) zero
pragati swain ...okay i guess the answer lies in first line of question that since it is non commuting hermitian operator then [A,B]+=(BA-AB)+=[B,A]+ or -[A,B]+ i.e. anti hermitian operator ....and for antihermitian operator eigen value are imaginary
Those were my starting days of posting videos on RUclips, checkout new videos there's a night and difference.. Infact if content is good then these things doesn't matter

Super and easy explanation to prove that momentum operator is hermitian. I had watched many videos giving a tedious explanation for this.
Really amezing mam.tq so much.I've a lots of problem with quantum but after watching your video i really get benefited.
Thank you. Good to know that my videos are helpful to the students :)
For the past 1 hour searching the get the concept atlast found yours thanks. ...

Thank you for such kind words
sir can you give solution to kinetic energy operator
sir i have a question.. The 2s orbital of H atom has a radial node at 2a bcz sai2s is proportional to ? how to approach this question ?
+Sapna Barad I didn't get your question, please post the full question with options or tell me the year in which it came
sorry sir , not able to write a whole question .sir can i have your mail id ? so that i can send you the question .
Radial node= n-l-1
For 2s orbital it is 2-0-1=1 node
You are too good sir...Hat's off to you sir.. please keep making more videos.
Thank you. Yes I'll try

Is Hermitian operator present in Peter Atkins book sir please tell
No idea, this information will be more than enough
this is really helpful sir thank you
Hiii
Nicely explained. Kudos to your work. Keep going. : )
Thanks :)
In this case u write (-ih+)* = ih+,it is not clear to me, plz explain sir?

K.E operator comes out to be a positive quantity on solving which means its not hermitian..
Is it so??
Kinetic energy Operator is hermitian
How many of you solved Kinetic energy operator?
Hermition operator
no, anti hermitian
it is an hermitian operator ....thanks for the video ....a new concept for me ...

Tnk Q bro
Welcome :)
Ok
HELLO SIR!
PLEASE SOLVE THESE CSIR QNS
QN-1
A constant of motion is defined by the equation:
(a) [H, A] = 0 (b) =0 (c) A = f(H) (d) † A A
QN-2
If A and B are non-commuting hermitian operators, all eigenvalues of the operator given by the commutator [A, B] are
(a) complex (b) real (c) imaginary (d) zero
+pragati swain alright
pragati swain ...i think answer to ur second question is b) real if they are non commuting operators
pragati swain what is the answer?
Priyanka Kapoor it's given imaginary. I'm so confused. Net 2012 December
pragati swain ...okay i guess the answer lies in first line of question that since it is non commuting hermitian operator then [A,B]+=(BA-AB)+=[B,A]+ or -[A,B]+ i.e. anti hermitian operator ....and for antihermitian operator eigen value are imaginary
