Nhi bhai, woh exact hi hoga...M wale me x²-y² hai aur N wale me y²-x² hai ..toh minus(-) bahar nikalne k baad N wala x²-y² ban jata hai aur woh minus bahar jaake '-a' k sath multiply hoke +a bn jata hai ...toh isliye difference nhi aata aur yeh exact hi hoga
I am watching this 1 week before exam. I know this concept from the beginning. I am confident i can solve any exact equation. So i came here to take my preparation to a higher level
i don't get one thing tho,how are we supposed to know if the given differential equation in the question paper is only solvable by exact method and not any other method or vice versa
Bhai sir nai jo method kraaya hai usse exact aara hain pr jo tum kaha rahe ho usse not exact aara hai, mera bhi same , i am confused which one is correct.
6:44 Tha Equation is Exact. See carefully there is - (negative) sign in dy term ie; (y - ___)dy. Multiply that negative sign inside bracket then LHS = RHS
Ak to yea easy topic hai apse sikh kar or vi easy ho gaya. Sir up se meri ak question hai ki up itne bar student keheto ho (hame bohot a66e lagta hai yea 😇) up ghar me mistake korte ho ki nehi? 😅 . Matlab ghar me kavi kavi student keheto ho mistake se?
Sir your knowledge is excellent you teach very good .....but I thing I think is you can keep your speed bit low as if we try to understand 1st step you are already on 2nd one 😅
to those wondering if the second question is not exact, it is exact and i think u are getting the wrong answer because u are derivating N by dy instead of dx. try that. you will get : -a(y^2-x^2) /(x^2+y^2)^2 dont forget its dM/dy, and dN/dx
Sir can you tell the reason why we don't take x term while integrating the N term w.r.t y.....also sir when I integrate the N term with taking term as well it takes the same vale as M term and then the 2 gets on the other side giving c/2. While this is applicable in only a few questions.....it would be very helpful if you explain the derivation of formula
SIR YOU ARE GREAT PERSON MOSTLY I AM WATCHING YOUR VIDIOS BECUASE YOUR VIDIOS ARE HELPFUL IN MATHEMATICS FIELD ONE THING I WANT TO SHARE ALSO PERPARE VIDIOS FOR RESEARCH FIELD
Sir can you please 🙏🙏 discuss the lengthy method to solve such Exact Differential Equations.... Since I got to know that this shortcut method does not work sometime....
2 problem) dekho jinko bhi not exact araha hai. Sir ne M kardiya mai N karunga dekho aur samjho. N=y-(a²x/x²+y²). ( mere pass dow nahi hai to mai d bolunga samj jana) dN/dx=0-[((x²+y²)(a²) -a²x(2x)) /(x²+y²)²] = -[(a²x²+a²y²-2a²x²)/(x²+y²)²] = -[(-a²x²+a²y²) /(x²+y²)²] 'Minus multiply hoga bahar wala. = (a²x²-a²y²)/(x²+y²)² . =a²(x²-y²) /(x²+y²)² . Agayana both are equal.
@@solidmodlingsmtutorial8849 I tried that method also and also I got answer But That answer was wrong . (In short: this(exact and general solution) is a shot method to solve problem.) This is a sequence to be followed, 1)dM/dy=dN/dx (If exact then find general solution) And If dM/dy≠dN/dx (non exact) follow this sequence of methods (4 methods). That methods are hard to explain in this text 😅😅. Take from his conceptual lectures.
Sir aap plz thoda dheere samjayege asa lagta hai ki aap apne AAP ko hi samjha rahe ho bura mat manana lekin mujhe kuch bhi samjha nhi aa raha hai.aap samjayo na konse term kab lene hai.plz sir I'll request you
Option : B is Correct✔ (Not Exact)--> Because My = 3 and Nx = 4 that's why...
Bhag
Yeah right bro I also got this thanks for sharing 😄
Ya right ...not exact differential equation.
Yes not exact
You are write
Sir in the second problem it's not exact until a=0, a negative difference is coming while cheking exactness.
Thank your sir ❤️
Very useful sessions ❤️
Yes
Question hi change kar lo negative sign lagake ya toh likh do it's not exact so can't solve using exact method.

Optin B is correct - not exact
Thank you sir for this good lecture
in question number 2, 6:47 , dM/dy is not equal to dN/dx , so they are not exact differential equation.Hence No solution.
no they are equal just check once more
@@arkadipray1210 not equal i tired many times
they are not equal
Sir bohot achcha explain karte ho... ❤️
Option B is correct.. Thank you so much sir 🙏
You just saved my day today.....thanks sir!
6:44 Tha Equation is Exact.
See carefully there is - (negative) sign in dy term ie; (y - ___)dy.
Multiply that negative sign inside bracket then LHS = RHS
But when we shift the equation to lhs dy geta a -ve sign n dx become +ve so still there is a change in sign
Sir your videos is very helpful for us
Thanq so much for these videos 🙏🙏🙏🙏🙏🙏🙏👍👍👍

Sir ne M kardiya mai N karunga dekho aur samjho.
N=y-(a²x/x²+y²). ( mere pass dow nahi hai to mai d bolunga samj jana)
dN/dx=0-[((x²+y²)(a²) -a²x(2x)) /(x²+y²)²]
= -[(a²x²+a²y²-2a²x²)/(x²+y²)²]

'Minus multiply hoga bahar wala.
= (a²x²-a²y²)/(x²+y²)² .
=a²(x²-y²) /(x²+y²)² .
Agayana both are equal.
Why can't we simplify the values of m and n so we get different answers if we cross multiply? How did I get to do this like this on the exam?
