PYQs on Classification of PDE | CSIR NET 2011 to 2023 | GATE 1997 to 2023 | Short Cut Tricks

[@DrHarishGarg]

Dear students... Q2 of this video.... Its correct answer is "2nd one" due to "EXCEPT along..." It is hyperbolic except along y-axis, Explanations:
a) On x-axis, there exists x=1 or x = -2 then B^2-4AC> 0 , Thus, hyperbolic
b) On y-axis, x= 0 always, thus B^2-4AC = 0 always....Thus, hyperbolic not exist, although its parabolic.
c) on line parallel to y-axis, there exist x = -4 , or x=3, thus B^2-4AC>0. Thus, hyperbolic
d) for line parallel to x-axis; there exist line say y=2, y = - 3, etc;, then B^2-4AC> 0. Thus, hyperbolic

Sir pls make video based on COV(calculus of variation) ,it's my humble request pls

[@vahisht1]

I will recommend you to buy a really good quality mic, Blue Yeti will be perfect I think, Sir, the audio quality will then be on next level👍

[@himanshusoni2374]

One video on determinant

[@dhirendrakumarsahu2127]

Sir Q2. Option d correct as given (hyperbolic in entire except along .....

[@DrHarishGarg]

I recheck it.... Its correct answer is "2nd one" due to EXCEPT along... It is hyperbolic except along y-axis, because on y-axis, x=0 always, thus B^2-4AC = 0 always....Thanks

[@Na4asimha]

at 1:03:58 the calculation was mistake sir . but the option c correct .

[@murugangan3213]

Sir..measure theory..pyq series available?

[@somaghosh3151]

Sir please field theory and ring theory solve in 15 sec ki video daliye

[@a.shakila7171]

Thanks sir

[@ankitadangi1655]

12:25 sir apne postive y/x kyu lia .. negative kyu nhi lia

[@Radharanilove-y5d]

Sir please upload the vedios of modern algebra ...
Guys please do MSG to sir for modern algebra vedio

sir Part A ke PYQ's v solve kra digye.. please sir

[@sudiponchowdhury2341]

🔥🔥

[@vahisht1]

01:04:01 you forgot to put 4 in the denominator for the value of C, so calculation part done is wrong, Sirji
