[QUOTE="compliant, post: 2432239, member: 176317"] [h2]Homework Statement [/h2] Given u_tt = F(x,t,u,u_x, u_xx), give the finite difference approximation of the pde (ie using u_x = (u(x + dx; t) - u(x - dx; t))/(2dx) etc.)[h2]Homework Equations[/h2] Well, clearly, u_x = (u(x + dx; t) - u(x - dx; t))/(2dx)[h2]The Attempt at a Solution[/h2] I really have no idea how that formula applies, but I [b]do[/b] know that u_tt = u(x,t+dt) - 2u(x,t) + u(x,t-dt) / 2(dt)^2. How the non-homogeneous term F applies, I have no clue.I'd be eternally grateful for any help anyone has to provide...considering I was the only person to reply to my last thread (on PDEs.) [/QUOTE]
