    Solving PDEs with Shocks: Analyzing Solutions

    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

    Solving PDEs with Shocks: Analyzing Solutions

    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...

    PDE with constant coefficient using orthogonal transformation

    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...
