🔵24 - D Operator Method for Solving First Order Linear Differential Equations

[@TochukwuAbel]

Great one Simplified ❤❤❤❤❤

[@SkanCityAcademy_SirJohn]

Thanks so so much

[@AbideChauke]

can you please explain why you multiply the top by x every time you differentiate f(D) and also why D^2 =-a^2 for sin and cos functions

[@osaisahmed]

Because of linearly dependent solutions (particular sln and complimentary sln)

[@MoabiSehapi]

Very helpful thanks❤

[@SkanCityAcademy_SirJohn]

You are welcome

[@Excellingdaily]

Great job. Please which apps do you use for your video?. Thank you

is it applicable when the G(x) is a polynomial, say 10-0.05x

[@SkanCityAcademy_SirJohn]

Can you please be specific, you can state the time in the video

[@greepykhan8557]

@@SkanCityAcademy_SirJohn with the alternative approach: let’s say my g(x) = 10-0.05x rather than the exponential x

Amazing

[@SkanCityAcademy_SirJohn]

That's great

i had y=c_1e^{\frac{3x}{2}}-\frac{3}{13}\sin \left(x ight)-\frac{2}{13}\cos \left(x ight) for the second one

[@SkanCityAcademy_SirJohn]

I'm not getting how you've presented it. Ignore frac and just present it well okay.

​@@SkanCityAcademy_SirJohn Surely a computer science student

[@TeofilWhite]

@@AFCOE Just use a LaTex interpretor.

[@SkanCityAcademy_SirJohn]

Ok

[@engsmyle]

Sir 😢, can you teach us the rule for finding that particular solution with D-OPERATOR, like more example ❤️❤️

[@SkanCityAcademy_SirJohn]

Kindly check video 25 if that will be enough. Where do you watch from?

[@engsmyle]

@@SkanCityAcademy_SirJohn I have watched it sir, is there any rule we must consider for determining it with D OPERATOR, if you can tell me name of any bool I can learn it from I will appreciate that

[@SkanCityAcademy_SirJohn]

Well, you will not find all in any book, it depends on the type of question you get

[@engsmyle]

@@SkanCityAcademy_SirJohn okay 😔 , thank you sir ❤️❤️

[@SkanCityAcademy_SirJohn]

You are welcome

Please try to step up a bit so that we can catch up before the exams on Tuesday

[@SkanCityAcademy_SirJohn]

I will try my best...

[@QaisDib]

you have d^2 = -1^2 = -1? how is -1^2 = -1, its supposed to be 1

[@SkanCityAcademy_SirJohn]

D² = -a² not (-a)².... Take notice of that.

[@anshverma7031]

It's( -)of a^2

@anshverma7031 thanks for you contribution
