How do i plot a graph  of  (H .vs. X/(2.Pi.sqrt(2))) for different values of time =t

H is the film thickness

When I plot my values, I get a normal graph of H .vs. X, but I need to see the above mentioned graph.

Please suggest solutions.

The command which I wrote for my graph generation, looks like this:::::::::

> IBC := {h(x, 0) = 1+0.1e-2*sin(x/sqrt(2)), (D[1](h))(0, t) = 0, (D[1](h))(2*Pi*sqrt(2), t) = 0, (D[1](D[1](D[1...

Can anyone explain the method that was followed in "Box Discretization" scheme in Maple Help?

Am trying to discretize 4th order terms in space..... d^h/dX^4 and third and second order in the same way....

I would like to know how to program this equation in MAPLE to iterate and derive my results (values of "h") in the form of plots....

I would like someone to take a look at my equation and tell me if its solvable...coz am not able to graduate!!!! :(
