PYQs on Calculus of Variations | Short Cut Tricks| CSIR NET 2012-2023

[@nil9428]

16:45 option (2) is correct P.I = +1/2sinX
18:23 natural Boundary Condition to be applied for whichever condition is not prescribed. Here you have to put at x=2 and not at x=1.

[@SADDAMHUSSAIN-mw3cv]

16:35 Correct option is (2).

[@Gayanibaba_in_math]

16:46 calculation mistake to write the differential equations so option 2nd is true

[@SADDAMHUSSAIN-mw3cv]

Yes. Correct option is 2nd one.

[@komalkapoor3488]

Yes option 2 is true

[@kungumsraj3026]

Excellent way of explanations for all the questions... Thanks for sharing

[@mr.bhushanbalpande5110]

Dear Sir ..... at 6:40 the question you have discussed is from CSIR NET Dec 2016, Part C, and the correct options are (A) and (C) ..... I think you are making it in a wrong way ....... if it holds for some values then it is weak and if it holds for all then it is strong. In addition to this strong always implies weak ......... Please correct it .....

[@sandipsarkar9719]

Exactly... And if it is strong then imply weak but converse not hold.

[@kumaranand5084]

yes you are absolutely right I check this q ans in different pyq book

[@raghuvd1763]

You said correct. opt a and c are correct.

[@anitakaushik-be8mo]

Correcct

[@shifakhanam6298]

At 16:04 just an error of negative sign y''-y=-sinx.... So that option 2 is correct

[@yogeshjadhavpatil4120]

Great teaching guruji

[@DrHarishGarg]

Thanks...

[@rijudey8718]

16:52 option (1) is correct, I think. after using natural boundary condition.

[@jobinbaby8287]

Very helpful lecture

[@RanjangamingYT7477]

6:43 a,c option correct

[@sonaligoud-de1cj]

Thank you so much sir for your short tricks. 🙏🙏🙏

[@artidevi8628]

Thank you so much sir 😊

[@sandipsarkar9719]

Sir at 10:48,there exist some polynomial which is neither even nor odd. How can u say this there does not exist such unique y, please clarify??

[@virendrakumar6922]

thank you so much sir

[@ahsanmehmood5875]

Awesome

[@Indigenuos]

Thank you sir 🙏

[@DrHarishGarg]

Thanks

[@anupamsamanta6690]

Very nice 🎉

[@DrHarishGarg]

Thanks... I hope you can share with others.

[@SOMPALSINGH-ps9gl]

Dear Sir, according to myself the functional J[y] has a strong minimum. So option 3 will be correct. Please check it and clear my doubt.

[@shifakhanam6298]

Sir please mention the corrections as it is very helpful for us. Thank you❤

[@DrHarishGarg]

Noted

[@mukeshlalit5152]

Yes you told opposite

[@savitrikuldeep]

Sir please check question no 4 where you discussed maxima and minima there is some problem please check I think strong and weak minima both the correct

[@pinakroy5928]

Yes you are right

[@factsgenius3333]

No it's alright, strong minimum=> weak minimum but Converse need not be true.

[@pinakroy5928]

Definition wrong for strong and weak

[@kartik3535]

Both strong and weak should be there

[@piyushpandita8016]

Thanks ​@@kartik3535

[@SouvikDas-rw7rp]

sir in the third problem one boundary conditions are given then why natural boundary conditions use?

[@joymath5588]

Nice

[@ronneysaini7763]

Sir Integal Equation nd Numerical Analysis Also🎉Alsop

[@debajitroy7300]

37:07 Y"-aY solution???
I think not correct

[@someshnogia2009]

25:55 the option (c) is correct.
b is not write ans.

[@januaj5268]

Explain your reason

[@asimdas2571]

Probability and statistics pyq solution plz

[@subramaniv6791]

Sir polytechnic trb question upload sir

[@rishebbarwal6344]

16:03 not sinx its -sinx

[@nishajyoti5896]

👌
