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.
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
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
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?
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 .
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🙂
