Exact DE Involving Trigonometric Functions - Differential Equations

[@jelivinontulan146]

Honestly, I'm here kasi exam namin this friday sa DE at I know na mahina talaga ako sa any math problem pero dahil sa video natu alam ko na pano e solve ang DE. Thank you Engr. 😊

[@hooplahoopla3473]

Thank you for the lessons, sir. Yung pageexplain nyo ay sobrang linaw at maiintindihan mo talaga. May exam kami sa DE tomorrow and I will use your methods to get the solutions. You just earned a sub!

you keep saving me from my modular self study life THANK YOU!

putting scriptures in the heading of the tutorial, thumbs up. The Lord grant you more grace sir

[@jbalfonso2600]

maraming salamat as mga lessons, sir. malaking tulong po kayo lalo na ngayon online class, di ko masyado naiintindihan ang differential equations., mabuti nalang nandito mga videos nyo. more power po, sir!

[@ajalvinagravante5426]

Legit yung mga lesson mas na iintindihan ko pato kesa sa lesson nang prof koooo

[@alexhinemisha7989]

Sobrang helpful sir!❤️

[@VizionzBlur]

my man. thank you so much.

Please the direvative of the angle ( xy) is ydx so the integration of ycos(yx)dx=sin(xy) directly ok Thank you

[@clayton3518]

how about yung other side sa equation ay may function of x and y. E ignore lang ba yun or dapat isolate talag ang x at y?

[@vanbeethovenvillanezo2875]

What if sir the Q(y) is not containing purely of y variables?

[@abatandchill]

Might be a wrong solution

[@vanbeethovenvillanezo2875]

@@abatandchillso i must eliminate first the x variables before getting the values of Q(y)?

[@abatandchill]

No, when you have a right solution for exact, there will always be a Q(y) purely in terms of y, or a constant or zero

[@vanbeethovenvillanezo2875]

@@abatandchill Okay sir. I assume there might be wrong in my solution thank you.

Bakit sa number 1 lang inapplyan ng product rule sir

[@rhandolfryanbucol3925]

Halimbawa po kapag doon sa Q(y)=xy ano po gawin kapag may two variables pa diyan or ganun talaga?

[@abatandchill]

Q(y) should be purely in terms of y, or a constant or zero. Check again your solution

[@darynehannahalilam7088]

May sample problem po ba kayo ng non exact na trigo sir??

[@user-ml7nt2sq9f]

Hi, sir will it still be considered not exact even if the only difference is the sign?

[@abatandchill]

Yes. Still not exact.
