thank you so much sir s tutor....dami aq natutunan lalo n ngayong pandemic....kht hnd n ako mgklase basta makapanood nlng po ako s video u....again sir thank you and advance...
As an engineering student, this video helps me a lot, I mean all of your videos Sir. Thank you and keep making videos like this that can help a lot of students like me. More power and God bless you Sir!
Good day sir! I am very grateful to you because you are sharing your knowledge to us. The learnings material that we have in online learning is not sufficient but with your videos and an excellent teaching skills I am able to understand our topic.Thank you sir.
Hello, sir. I have been watching your videos the past days and it has been a great help to me ever since. I have just noticed one minor error from your vid around 33:39 where you omitted the variable 'x' after simplifying -4x[y^2/2]. You wrote -2y^2 instead of -2xy^2. I think Q(y)=R(x)=0 is the case here since x^2y^3-2xy^2 are on both sides of the equation and thus, x^2y^3-2xy^2=c.
First of oll thank you. Sir there are some important topics missing from differential equations like: Equations solvable for p, y and for x. Clairauts type. Please do upload them.
My method during my college days is: Test first if its variable separable, if not then check if its homo, then test for its exactness etc. It takes familiarization and practice to be able to know what method suits to solve the DE. Hope this helps
Can u make hard problems sir...I have a lot of problems here ... And I don't know how to answer this ,using your way... Coz my instructor...has his another way to solve a non exact DE problem... And I don't know which way I might use...
Can you solve this DE? ( 2x-y^2sinx-x^2sinx)dx + 2y dy = 0 ; I arrived at : integral of 2xe^cosx after getting the integrating factor. I think e^cosx cant be intègrated if I use IBP! Any technique? Tnx
may I ask , why the integrating factor for the formula of the funtion f(y) has a negative sign? my teacher gave likewise to your given formula but it has no negative sign
Sir Thanks for the Vid. mas nagets ko pa yung Explanation mo kesa sa Prof. ko Hahahaha. Tanong ko lang kung pano madedetermine kung yung Equation is for Exact or Non-Exact? Thanks in Advance.
Hayst sir the corrections 😅😅😅 hahaha puro bura na po ako at nagcocopy po ako hahaha laging May correction si sir 🤣 pero at least hahaha salamat pa rin po sir Abat hahahaha okay na may mga bura at least naiintindihan ko ang tinuturo 😍
sir, question po yung nasa book po kase hindi po negative yung integrating factor formula for case 2. pano po yun sir? kase magkaiba po kase makukuhang answer.
f(y) = (1/M)(dN/dx - dM/dy) kasi siguro dun. kung i negative mo same lang pero magiging f(y)= -(1/M)(dM/y-dN/dx), yung form na ginamit ni sir Yu Jei Abat. Late pero baka makatulong sa iba
That's my answer as well because there are still 1/2 left in my equation. But why is the answer to the problem is this? Can someone help please? x^2 y^4 + y^6 - 10y^4 = C
Thank You very much for this SIr Engineer, But one question lang po, what about po yung case 3? CASE 3: WHEN THE INTEGRATING FACTOR IS A PRODUCT OF POWERS OF THE VARIABLES X AND Y u=x^k * y^n Thank You,
Answer to the take home problem:
x^2 y^4 + y^6 - 10y^4 = C
yooown, Tamaaa, Thank you very much po Sir :)
Sir can you show me the solution?
tama po kami thank you po :))
Thank you sooo much sir 🙏🙏
salamat po sir big help !!!! also got the same answer :)
Thank you for the knowledge Sir as an engineering students we highly appreciate it.. stay safe and God bless
This was wonderful for real.
I appreciate your detailing, your step by step method, the whys and hows.

Galing nyu po mag explain sir. Salamat po sir and Godbless
Hello, may i ask. How to determine if the given equation is variable separable, homogenous or exact. ?
My method during my college days is: Test first if its variable separable, if not then check if its homo, then test for its exactness etc. It takes familiarization and practice to be able to know what method suits to solve the DE. Hope this helps
@@abatandchill sir wala po bang cue or something para mas mabilis mo sya ma identify kung anong problem ung given ?
You the real maths god..😘😍
thank you po sir!
I love the bible verse on the screen..great video!
Heroes don't wear capes now. They save Math class
Thank you so much it is very helpful for students Like me...
Your the best po ❤️ godbless po
thank you so much sirrr you save me from my quiz!!!!
Can't you just do a variable separable on the first question? (did it in 5 steps.)
Salamat po ulit sir!
Thank You po!! Super helpful
(1+y^2 )dx+ln(1+y^2)+C
please answer this on your next video
Can u make hard problems sir...I have a lot of problems here ...
And I don't know how to answer this ,using your way...
Coz my instructor...has his another way to solve a non exact DE problem...
And I don't know which way I might use...
I will try my best on this.
Thankyou Sir for your contents/videos.
Sir your the best!

Yuhooo thank you so much sir!
Bravo
Thanks a lot
I can now do it
New subscriber po sana may video po kayo about summation of moments sa mechanics po
Soon!
Salamat po
thank you so much sir!
Can you solve this DE?
( 2x-y^2sinx-x^2sinx)dx + 2y dy = 0 ; I arrived at : integral of 2xe^cosx after getting the integrating factor. I think e^cosx cant be intègrated if I use IBP! Any technique? Tnx
x^2 y^4 + y^6 - 10y^4 = C
thanks so much
please can you make videos on riccati differential equation, near homogeneous, initial value and boundary value problem.
I will try my best. Thanks!
Yu Jei Abat thanks so much
may I ask , why the integrating factor for the formula of the funtion f(y) has a negative sign?
my teacher gave likewise to your given formula but it has no negative sign
Its the same. Given that you will also have to get the difference of partial of (Nx - My)/M.
thank you po
Hello, are there any videos on 2nd order differential equations ?
thanks a lot for your efforts!
Soon!
Thank you so much !
I.F. = y³
Ans is :
x²y^4 + y^6 - 10y^4 + x²y = C
Is this correct sir?
Please try again :)
2(2xy+4y-3)dx + (x+2)^2dy=0 pano kung ganito sir. sinundan ko po yung process nyo sir kaso ang hirap nung integrating factor nya.
Thank you sir.
bakit may negative ang integration factor ni function of y? sa books po wala.
Sir Thanks for the Vid. mas nagets ko pa yung Explanation mo kesa sa Prof. ko Hahahaha.
Tanong ko lang kung pano madedetermine kung yung Equation is for Exact or Non-Exact?
Thanks in Advance.
Watch mo ung "exact DE" na video ko. :)
Yu Jei Abat Napanuod ko na sir. Maraming salamat. medyo nalilito pa ako sa Non exact. Salamat ng maramo ulit sir. More power !!
I.F. = y^3
x^2y^4 + y^6 - 10y^4 = C; C=2C
Is it correct?
Yes this is correct :)
God Bless sir!
God bless you too!
Sir i hope u'll make a video about bernoulli de. ^^
Sure. Soon!
Hayst sir the corrections 😅😅😅 hahaha puro bura na po ako at nagcocopy po ako hahaha laging May correction si sir 🤣 pero at least hahaha salamat pa rin po sir Abat hahahaha okay na may mga bura at least naiintindihan ko ang tinuturo 😍
Sorry na. 😂
@@abatandchill hahahahahaha okay lang sir hahaha God bless po palagi sir
Thanks po sir
You're welcome!
Sir paano po pag ginamit na po yung dalawang case pero mix variables parin po yung naging result
thank you engr.☺️
You're welcome!
Good evening Sir, what will be the final answer here? the answer from Non exact DE or the answer that we get from the exact DE?
From the exact DE
@@abatandchill Thank Sir ♥️
sir, we can intergrate either df/dx or df/dy right when dm/dy is exact to dn/dx?
Can right sir?
hope electrical circuit 1 next 😊
Will you share it with your EE friends and classmates who are taking circuits? I'm afraid it does not get atleast 1k views.
@@abatandchill electrical circuits po sir please! almost lahat po ng kaklase ko kayo po pinapanood para sa subject na DE hehe online class struggle
hello po ano po ang ginagamit nu pong applicarion sa gnyan pogn presentation po un may powerpoint n solution na may video dn nu po
2x^2y^4+y^6-10y^4=2C pa check po sir?
hello po engr. pwede po magpatulong sa equation na ito.
(y+x^3+2x^2)dx+(x+4xy^4+8y^3)dy=0
maraming salamat po.
What is the the simplification of e raised to -ln(sinx)
A. Sin^-1(X)
B. Sin (x^-1)
C. (Sin X) ^-1
D. -sinx
C
C.
e^(-lnsinx) given
=e^(ln(sinx)^-1) law of logarithm

You're a grade saver. huhu 😭
Thank you
Wow thank you so much! 😊
Thanks bro🙏
10:30sec
Ready to see magic? Yes Let's go 🤣🤣🤣
Sir tama po ba IF is y^3 then final answer is “x^2y^4 + y^6 - 10y^4 = C”?
Yes this is correct :)
X^2 +Y^2-10=C/Y^4. ?
sir, question po yung nasa book po kase hindi po negative yung integrating factor formula for case 2. pano po yun sir? kase magkaiba po kase makukuhang answer.

(y-xy³)dx + xdy=0 how to solve this problem po?Can you help me?
Sir, Reduction to Exact DE po ba ito?
Can we use this in all of the DE problems?
Yes for Non-exact DE
So its like an integrable combination sir, iba lang ng way of solving
Yes
ANSWER: y^4 x^2 + y^6=C
Try again
sir nagkamali po ba kayo sa formula ng case 2
Nope
Integrating factor by inspection nga po sir
Soon.
INTEGRATING FACTOR =y³
2C=x²y⁴+y⁶-10y⁴
That's my answer as well because there are still 1/2 left in my equation. But why is the answer to the problem is this? Can someone help please? x^2 y^4 + y^6 - 10y^4 = C
Thaaaaaankkkkkkkkksssssssss 💓💓💓💓
You're welcome!
lnx²y⁴ + y^6 - (5/2)y⁴ = c ...?
Try again
Thank you sir 〒_〒♡
Where are you from sir
Hi! From Philippines, and you?
I am from India your style perfect teaching
Thanks, kindly share it with your engineering friends!
Thank You very much for this SIr Engineer,
But one question lang po, what about po yung case 3?
CASE 3: WHEN THE INTEGRATING FACTOR IS A PRODUCT OF POWERS OF THE
VARIABLES X AND Y
u=x^k * y^n
Thank You,
I will be uploading a video about this one thanks!
@@abatandchill very much appreciated po sir engineer
Are you Filipino?
Yes.
ah kaya pala.. Ganda po ng mga examples nyo
Wow. Thank you!
Sir pinoy po?
Yes
Very slow. Make it faster.
Hi, this video is designed for those who have zero knowledge in this topic.
@@abatandchill Then, it is okay. But, I am at the last stage of my exams perparations. But no problem, I have gone through other videos.
Thank you Sir!
