## thanks!!!...

@Carl Love thanks a million!!! i have been playing around with different forms of the wave equation try to figure out how to model ripples over a smooth surface.

i haven't be too successful though!! its killing me

any recomendations?

this is what i have so far!!

this is more or less what i want but i am try to do this but within an rectangle instead of a circle, is this possible?

## thank carl...

i realized that after a i figured out the 3d plot.

what if we change the original equation to a pde

with the derivative on the left hand side to a derivative with repect to t?

## its works!!!!...

@Carl Love thanks carl!!! can this function be animated in 3d?

@Carl Love thanks carl!!! can this function be animated in 3d?

## ok thanks!!...

@Carl Love what kind of boundry conditions would i need to find these arbitrary functions???

## but if i just use .........

but if just use

pde :=

s:= pdsolve(pde);

with no boundry or initial conditions

i get :=

## interesting!!...

i'm trying to do the same thing but animating in 3d???how can i do this ... to show something like waves cuased by a stone thrown in a pond?

## animate...

@Preben Alsholm how can i animate this but in 3d using polar coordinates??

how can i do a 3d plot of this equation to see its behavior???
