43:12 you said that there is no solution but when you solve the problem getting quadratic in u this implies 2 solution exists. Then what is the meaning of No solution unique solution infinite solution formula. Please reply sir
Good evening sir I like your teaching I appreciate your help sir We are grateful for your shortcuts to clear CSIR NET exam In 13.21 how do you choose C1 become 1 Can you explain please
Sir question no 97 per upne u=pi(t)u_0 kue Lia. Upne bola ki u_t and u_x ka coefficient constant hona chahiye. But u constant hoga ki Nehi yea upko kaise pata chala.
In 18.53 problem 94, Dec 2015 , Second method the complementary function the solution is C1 cos wt + C2 sin wt will come sir It is not a real root But you write it a complementary solution is wrong i think Can you clarify my doubts please
Sir, I am confused whether the trick works for only heat and wave equations having f(x)= sinx , cosx or e^x only. Does it work for all higher order pde? Does it work for Laplace equations as well?
Sir in many of question this trick of putting values of x and t from the coefficient is going to fail.... So please don't give that types of trick because when jo ques hame aa bhi rha hoga hm tricks ke chakkr mai aata hua ques bhi glt kr denge.... Thanks🙂
Please correct Q. 95. Its answer is option (b) and (c) and not (d). I have checked it on NTA CSIR NET website. How come option (c) can be wrong, and if it is so, then your trick is wrong. Please check your answers before uploading the video ......
In 2018 NTA give the wrong answer. B, C but the correct answer is B and D , Don't depends on NTA answer key there are so many times NTA give wrong answer key when those students complaint against it they got mark. Correct answer is B ,D and sir is wright .
3:25 .correct option is (4)
I really want to thank u sir for making this video.
Thank you so much for this helpful video
Sir aap great ho kya trick hai aapki jo kuch clear nahi ho raha tha bo bhi aa gaya samajh me thank you so much sir ❤
21:04 .correct options (2), (3).
Respected, sir you are requested kindly upload the Part 2 vedio . Very thank you for the Part 1 vedio .
Sir plz make a separate vedio for short trick formula of all subjects linear,real complex
Thanku so much sir❤
Thank you so much sir ❤
Thank you so much for excellent class ❤❤❤❤
Thank you so much sir
Thank you very much sir its very helpful now as exam is nearer 😊
Thank you so much sir🙏
Thank u sir 🙏
Sir please provide videos on Real analysis & Linear algebra short tricks
4:30 option d correct
Yes
Thank you sir
Excellent sir
43:12 you said that there is no solution but when you solve the problem getting quadratic in u this implies 2 solution exists. Then what is the meaning of No solution unique solution infinite solution formula. Please reply sir
Sir need of the hour is
2nd part of ODE
and 2nd part of PDE
Good evening sir
I like your teaching
I appreciate your help sir
We are grateful for your shortcuts to clear CSIR NET exam
In 13.21 how do you choose C1 become 1
Can you explain please
very nice
Sir, trick discuss in question no 94 is not match with question no 45. ans of question no 45 is a but according to trick ans is c.please check
Sir question no 97 per upne u=pi(t)u_0 kue Lia.
Upne bola ki u_t and u_x ka coefficient constant hona chahiye.
But u constant hoga ki Nehi yea upko kaise pata chala.
Sir question 95 per upne pahle dikha no solution.
But fir Two solution kaise hua???
Sir please check 95 answer ..the answer must be
Options b and c
In 18.53 problem 94, Dec 2015 , Second method the complementary function the solution is C1 cos wt + C2 sin wt will come sir
It is not a real root
But you write it a complementary solution is wrong i think
Can you clarify my doubts please
Sir real analysis mey bhi ak..dijiye...
If you find roots of m^2+2m+1=0 ,we are getting -1,-1 so solution must be y-x form
Yes. In Q 2 na
@@sidharthamedhi1224 PDLI
21:14 , option (b) & (c) correct ,
Sir sometimes you are taking like x-2t=0 implies x=1 and t=2 and other times you say x=1 and t=-2. I don't understand. Please help.
Sir, I am confused whether the trick works for only heat and wave equations having f(x)= sinx , cosx or e^x only. Does it work for all higher order pde? Does it work for Laplace equations as well?
You must watch my videos on HEAT and WAVE equations, you will learn alot and your all queries will solve fully.
@@DrHarishGarg thank you so much sir 😃 I'll watch them definitely. Thank you for all your videos. Glad that I found your channel.
partial differential equation ar Laplace equation short trick video send
❤❤❤
Sir Fourier transform sine and cosin transform per ek lecture do
Sir CSIR NET June 2017 k ODE & PDE k question solve kariye
Dec 2020 ,sir D = B^2-4AC
1). D= 4-4(1-sgny)
But sgn(y) = 1 if y>0
=0 ify=0
=-1 if y0 then we have sgn(y)=1
Imply D=0
Parabolic
When y>0 then sgn(y)=1 so D =4-4(1-1) =4-0=4>0 ... I hope it clear.
Thanku sir
I think in q 45 option c is correct sir I think there is a calculation mistake
Sir 42 question me d option bhi to ho sakta hai
Q.95 csir net dec 2018 1st you says no solution than you find two solutions how it is possible?
Yes....sir said option B and d are correct but option B and C are correct solutions
Sir kbtk ayega second part ODE ka
CSIR-NET -Dec 2011
Q: 48
Option 4 is correct
Option 4 is correct right??! I solved and it comes out 4th option ( I solved this question by putting D = m and D'= 1)
4.25 option 4 is correct
Question 48 ka answer to wrong h ,i think ,please check, option d is correct answer
9:56 Q.45 option 1 is correct ans.
Sir 48 answer is option 4 sir ...not option 2
Question no. 48 option 4 is correct answer
13:58 where is c1 i don't understand please reply sir 😢
Put the condition c1=1
Sir iski pdf kha milgi
101, u(x, t)=-x^2+t
Ut+(Ux)^2=/1
sir 7:06 option 3 correct hay. quiki x=iw,t=-iw^3 then satisfied equation...thna you sir
In 7:15, question 45, option C is correct. i^3=-i
Question number 45 ans zero hoga सर
Sir in many of question this trick of putting values of x and t from the coefficient is going to fail.... So please don't give that types of trick because when jo ques hame aa bhi rha hoga hm tricks ke chakkr mai aata hua ques bhi glt kr denge.... Thanks🙂
You are right 👍🏻
In question 96 why you only take c is zero .why not a and b will be 0 how you decided to take only c is 0 even that passing through (0,0,0)
Yes you are saying right... Ans of that ques will be 2,3,4
In this liner equation putting x=0,y=0,z=0 we get c=0
And answer is not zero as value of z=1/a nonzero so b,c,d may true
Sir dec 2017 , question -95 ka b,c correct answer h full solve krne pr
Yes
Yes ...b and c are Correct
Question no 48 me answer D aayega
13:21 how value of C1 becomes 1
Conditions de rakhi hai na jo usko satisfy kralo to c1 ki value 1 aayegi
In 13.21 , Questions number 100
Mera 1 &3 aaya
Please correct Q. 95. Its answer is option (b) and (c) and not (d). I have checked it on NTA CSIR NET website. How come option (c) can be wrong, and if it is so, then your trick is wrong. Please check your answers before uploading the video ......
Yes, question number 95 will be option b and c.
In his trick coefficient of x,y takes as it is given in the option not needed to be equal to 0
In 2018 NTA give the wrong answer. B, C but the correct answer is B and D , Don't depends on NTA answer key there are so many times NTA give wrong answer key when those students complaint against it they got mark. Correct answer is B ,D and sir is wright .
But b and c is right ans
Sol the question with the help of method
Thank you so much sir 🙏
I takes 3:30 hours to complete this video
Great..... You learnt alot from the video after spending time....
Excellent sir, your god of all csir aspirants, put a sepated play list , 2011-23, finally love you sir ❤️
Ek baar check kr lijiye
Sir 48 wala aapne mistake kr diya
4 option ayega
Yes option 4
Yy yha trick glt ho gyi …complimentary fun. Glt h
