Okay what am I doing wrong here?  It's an examination of the simple 1-d heat diffusion equation in a rod with homogenous boundary conditions.  I'm looking for the temperature distribution over a thin rod with unit length 1.  Both ends are held at 0.  And the initial temperature distribution across the rod I have set equal to x, with the diffusivity k=1/10.

So first set up the 1-d homogeneous heat equation
he:=diff(u(x,t),t)=k*diff(u(x,t),t,t):

I was curious about converting between the different ways of writing a derivative in maple for the standard GUI.

I can convert y' to D(y)(x) but I cannot directly convert y' to the form d/dx y(x) unless I go to the
tools->options->display and change the typsetting level to maple standard and reprocess the line.  We are stuck with either one form or the other but not both without having to adjust the typsetting level in...

I want to search maple files for specific texts within the file.  What software will do this?

I recall some mention before about searching for specific texts in maple documents but I cannot find it. 

How can I save a webpage as a text file? Not the source code. When I save a webpage from I.E. as a text file it seems to strip out a lot of the source code and I end up with a simple text file. Take this wikipedia webpage as an example http://en.wikipedia.org/wiki/List_of_HTTP_headers Now if I use Maple it grabs everything on the page, source code included which I do not want. Is there an easy way or must I create some code in maple (http surgery so to speak) to strip out the excess?

I want to change the direction of the tickmark labels.  As far as I know, only the axes title labels can be oriented with labeldirections=[horizontal,vertical]. 

Can the tickmark labels along the x axis be vertically oriented?
