🔵12 - Exact Differential Equations (Solving Exact Differential Equations)

[@Only1retro]

nah ,ive watched all the videos on differential ,this is straight to the point, the best

[@Only1retro]

i can now teach someone,

[@SkanCityAcademy_SirJohn]

Nice....

[@SkanCityAcademy_SirJohn]

Thanks so much.

[@reamabdulsalam524]

Really I don’t know how should I thank you , you are the best tutor ever please do post more videos , you make my life easier I felt that I can’t solve the exact equations and started to get depressed by checking other tutors videos , but once I see yours ohhhh my god too easy , others make it too difficult!!!!

[@SkanCityAcademy_SirJohn]

Awww thanks so much for your comments

[@sulaymaneabdulqudus9367]

I have been searching for exact differential videos on TH-cam and all I found was not explaining enough. But your video actually explained it to me more than I expected.
Thank you very much

[@SkanCityAcademy_SirJohn]

You are most welcome

[@favour-ot4nq]

Thanks aloot sir🙏🏽. You made it very clear not like my lecture going around the bush and bringing in new stuff everytime you ask a question 😥. Thanks alot🙏🏽🙏🏽🙏🏽

[@SkanCityAcademy_SirJohn]

You are most welcome
Thanks for watching

[@Yeno__429]

And my lecturer was confusing the whole class with nonsense.. I can't thank you enough dude 🎉🎉

[@SkanCityAcademy_SirJohn]

thanks so much

[@mondayizuchukwu2733]

Teaching is a 😢gift and teachers are gifted to students.

[@SkanCityAcademy_SirJohn]

Amen 🙏

[@kazitazrianmon6991]

Thanks so much! Really cleared the whole concept!

[@SkanCityAcademy_SirJohn]

Aww great. Where do you watch from?

[@al-washisarkerturan8913]

The best video on youtube on exact D.E.You have literally saved my final.TYSM.
Suggestion : Using a black background would be better for those who need subtitiles.

[@SkanCityAcademy_SirJohn]

Thanks so so much🎉🎈, and suggestions well noted....

[@gracepeterson1556]

Watching this literally 20 minutes before I go to take my exam and it finally makes sense...lol thank you!!

[@SkanCityAcademy_SirJohn]

Good luck Grace.where are you watching from?

[@kevinonyango-jk6ie]

I fully gotten the concepts of exactness method s except on derative of cosx is -sinx on questions 2

[@SkanCityAcademy_SirJohn]

Thanks so much

[@nyarkofelicityserwaa3031]

Please I used this approach to solve a question but I want to know in a situation where the coefficients of the common function are not the same how do you go about it? ie when merging integrals of Mx and Ny.

[@SkanCityAcademy_SirJohn]

If you have a typical question kindly send it to me.

[@nyarkofelicityserwaa3031]

So should I add the coefficients or just take one function ?

[@SkanCityAcademy_SirJohn]

You know it's rare to get such situations, so I just want you to send me the problem then I confirm at my end

[@lonlee9426]

Please which book did you get the questions from?🥺

[@SkanCityAcademy_SirJohn]

Schaums outline of DE

[@ericoduroboateng5269]

please can it also b in the form M(x,y)dx - N(x,y) = 0 or
is always positive(the sign)

[@SkanCityAcademy_SirJohn]

Actually it's supposed to be +, but if it's minus, it literally means that the N(x,y)dx function has a negative beside it. That's all

[@hensleysapom3525]

Okay, question here. Why to merge the two functions and write each only once?

[@SkanCityAcademy_SirJohn]

Yes that is a rule we need to just follow when solving exact d.e's

[@hensleysapom3525]

Okay sir. That's a very short way than the one in my lecture. Thanks, anyway.

[@chairmanosa2304]

Thank you very much for the video, but i will like to ask, incase you are merging, and you find your answer in both Mx and Ny but with different operational signs how will u go about that.

[@SkanCityAcademy_SirJohn]

its very rare for such situation to occur, anyways if you have a question like that you can bring it up so i try at my end

[@mensahbenjaminrabby3303]

Good video, simple and easy.
But please i also thought of that same question @Felicty asked. I don't have any example though but I will like to see conclusion on that when anyone finds out.

[@SkanCityAcademy_SirJohn]

Okay. Will let you know when she responds finally

[@lekissdarams7195]

Thanks bro! Even a kindergartner will understand 🙌

[@SkanCityAcademy_SirJohn]

Awww. thank you very much.
Please where do you watch me from?

This is lucid, Sir.

Thanks so much

[@abduljaleelsadiuba6717]

Beautiful tutoring

[@SkanCityAcademy_SirJohn]

Thanks so much Sadi

[@engsmyle]

Sir if the exact is in this form
M(x, y) dx - N(x, y) dy = 0
can the solution be
dϕ(x, y) = ∫ M(x, y) dx - ∫ N(x, y) dy

[@engsmyle]

Sir am I correct, I just think of it

[@SkanCityAcademy_SirJohn]

I've not tested that, to be on the safe side, make sure you put the d.e in the form M(x, y)dx + N(x, y)dy = 0. Do you understand?

[@engsmyle]

@@SkanCityAcademy_SirJohn okay sir ❤️

[@engsmyle]

@@SkanCityAcademy_SirJohn sir I would like to send a question 🙂

Determine the most general function M and N such that the equations M(x,y)dx + (2xy³-x⁴y)dy is exact.
