Also could you not use "chat room" slang? <--- Sorry !
Can you be more specific? <--- ok
For the PDE there is no solution except one case, what is this case ?
the proffisor said you can change something to have that case
why tensor analysis ?
Hi
Im studying tensor analysis this course but i don't know why we study it ? is it helpfull ? what is the history 4 it ? what tensor mean ?
:confused: :confused: :confused:
i hope i can find answer !
PDE + shock !
Ux + 2Uy = 0
I.C: U(x,y=2x) = exp(x)
solution:-
y=2x+c1
x=c2
using I.C
c1=0
c2=exp(x)
No solution since I.C on the characteristics line
every thing is ok until here but my teacher said that there exist one case that when u change some thing u will get a...
Thnx sir
but the dr. who teach me, didn't use this way with us
when we have aUx+bUy+cU=f , where a,b,c,f are constants
he take tan(r)=b/a
then he find r
after that take w=xcosr+ysinr , t=-xsinr+ycosr
then find Ux , Uy
that's it
so if i have aUx+bUy+cUz+dU=f
can i take same w, t...
Plz Help :(
Hi
I want 2 know how 2 solve 1st order partial differintial equation (PDE) with constant coefficient using orthogonal transformation
example :
solve: 2Ux + 2Uy + Uz = 0
THnx :blushing:
