First Order Partial Differential Equation

[@tamil575]

in final step how did t=x-2y, because the above assumption is t=x. I am not understanding that. can u explain me?

[@petercrowhurst4870]

This really helped thank you. Perhaps you might like to put something up on stability of different finite differences - forward time - forward space, forward time - backward space and Lax Wendroff -again thank you - this really made things very clear!

[@beetto_s2896]

agree with u mate, god damn, i just made one.

[@kornasurya4360]

Bro please upload more videos.. These are actually helpful for us...

[@azmathmoosa]

F(t) = Cos3t means that the function F(something) is actually Cos(3*something). So when that something is x, we get F(x) = cos(3x) and when that something is (x-2y), F(x-2y) = cos 3(x-2y).

What should i do when R = 0 than this system doesn't work

[@shivangidwivedi797]

Then dz shd be 0.. That means z is a constant

[@davidalormene4150]

This is a very good app. It is really helpful.

At 2:08, we cannot see the top 2/3 of the problem statement.

[@bellasckofeld637]

thanks for video is it a quasi linear form?

[@sarfokofi3515]

What if there was combination of x and y in the R term?

[@Zwaks]

How did b = F(t)???

[@aakash3752]

Why do u take constant a and b in right and left respectively

[@calvinjackson8110]

The second line you labeled the general solution. It is not. Can you suggest a text that developed the concepts of FIRST ORDER PDE'S step by step with the theory?

[@RobBabu]

Where did cos(3x) come from?? Seems to me like you whipped it out of no where.

[@qingshengzeng3898]

It's the initial condition, and you can only solve an nth order differential equation with n initial conditions

[@hermanodecaer2840]

Why are we aloud to use this auxiliary system?

[@shlokamsrivastava6782]

Thats a great video

[@NdeogoSalifuIssah]

I don't understand why you integrate 2y and only y² + constant

[@hermanodecaer2840]

Does this also apply in 3 dimensions?

[@miranda4907]

Hi, great video! When do you learn this? Is it in A2 maths?

[@mustafaawadelseed1962]

where is the rest of videos

[@رشادرشاد-م3ث]

صباحو ..شلون اخير الترجمه للعربي

[@saniaabdulbari1577]

From where did the cos function came?

[@axelmeramas976]

boundry conditions (initial conditions)

[@Banism24]

why put a and b only at y?

[@hype4283]

What if R is 0?

[@vvdurgaprasadvanka9140]

sir plz upload cauchy problem for first order pde

[@farhadali4726]

1:37 that exhust sound

[@joseluisarmenta]

i need to clear z one time with the constants and another with the initial conditions

[@kenzraldominance9250]

excellent well done thanks

[@axe863]

Yolo.

[@tejaanala5839]

osum vedio

[@johnschumacherAlphameric]

Badass!

[@calvinjackson8110]

Put up more examples that illustrate more general cases.

[@WriteRightMathNation]

Trouble is that his constant isn't.

[@annukumar7177]

thank you

[@joseluisarmenta]

so z will be the second memeber of the equation

[@pieacademy7994]

good

[@WriteRightMathNation]

His a should be a(x,y) and his b should be b(y,z).

[@dhawalrathour3991]

good move on

[@BlahBlooBlee4205]

dude, I wasted 7 fucking hours learning fucking nothing from the fucking shitty ass textbook; thank you for saving another 7 hours that I would have wasted

[@EngPMgt]

Henrik Panosyan same here i got confused with substitution !

[@mohamedjunaidhu1312]

F(t) = Cos3t means that the function F(something) is actually Cos(3*something). So when that something is x, we get F(x) = cos(3x) and when that something is (x-2y), F(x-2y) = cos 3(x-2y). --- I actually copied this from a comment below.

[@armatabuharilabaran5891]

+Mohamed Junaidhu am quite ok .

[@mariaprzedpeska2276]

kiwi

[@idreesi.m.m5973]

hi

[@soosais6679]

Nice one, please improve your speed.
