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).
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!
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?
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

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

What should i do when R = 0 than this system doesn't work
Then dz shd be 0.. That means z is a constant
Bro please upload more videos.. These are actually helpful for us...

agree with u mate, god damn, i just made one.
At 2:08, we cannot see the top 2/3 of the problem statement.
thanks for video
is it a quasi linear form?
Where did cos(3x) come from?? Seems to me like you whipped it out of no where.
It's the initial condition, and you can only solve an nth order differential equation with n initial conditions

How did b = F(t)???
Hi, great video!
When do you learn this? Is it in A2 maths?
Why do u take constant a and b in right and left respectively
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?
What if there was combination of x and y in the R term?
This is a very good app. It is really helpful.
Why are we aloud to use this auxiliary system?
I don't understand why you integrate 2y and only y² + constant
Does this also apply in 3 dimensions?
Thats a great video
1:37 that exhust sound
sir plz upload cauchy problem for first order pde
why put a and b only at y?
From where did the cos function came?
boundry conditions (initial conditions)
What if R is 0?
Yolo.
صباحو ..شلون اخير الترجمه للعربي
where is the rest of videos
excellent well done
thanks
Put up more examples that illustrate more general cases.
i need to clear z one time with the constants and another with the initial conditions
so z will be the second memeber of the equation
Trouble is that his constant isn't.
osum vedio
thank you
His a should be a(x,y) and his b should be b(y,z).
Badass!
good
good move on

Henrik Panosyan same here i got confused with substitution !

am quite ok .

hi
Nice one, please improve your speed.
