If you are using Maple12, take a look at the dsolve help page, in particular the numeric option callled "events".  At the Maple prompt, type the following, and hit the enter key.   Take a look at the examples.

?dsolve,numeric,Events

 The following link in Mapleprimes also has an example of usage:

The "display" command does not have an option to control the frame rate.  The "animate " command does.  Using the GUI to increase or decrease the frame rate is your only option when using the "display" command to create an animation from a list of plot structures.

Take a look at the help files for BarChart or ColumnGraph, both part of the Statistics package.

?BarChart

or

?ColumnGraph

Statistics[BarChart] - create bar charts from data
Statistics[ColumnGraph] - create column graphs from data
 

Try the following plot command and see if the output is the graph that you are expecting.

>plot(fmax,0..3);

On the menu bar, go to Format
Then select Numeric Formatting...

That worked for me, and gave me the same result as Classic.

The time function is a built in, so it is coded in such a way as to return only 3 digits. 

On my laptop, Core Duo @ 2 GHz with 1 G ram, I am getting times that range from 0.011 to 0.110.  It all depends on what the processor is doing at that point in time when you click the run button (!!!) on the menu bar.  

My commands look like this:

>restart:

>st:= time(): 3^1000000: time() - st;

0.011

 >?floor

or browse the help files and look for the "floor" command.

Using Google works, but if you do not have an internet connection for some reason, you can use "Character Map", which is built into Windows. 

Start-Programs-Accessories-System Tools-Character Map

or

Start-Run...

when the Run dialog box opens, type "charmap", without the quotes, and hit the enter key.  When you click on the u with the umlaut, you will see the keystroke necessary on the bottom right corner of the charmap screen.

Are you using a laptop?  If so, then you have to hold down the Fn Key along with the Alt key, and use the Blue numbers that are imprinted on the letter keys.  I am using a laptop, and that is how I did it.  On a PC, the above method should work, assuming the Num Lock Key is active.

Hold down the Alt key, and then type 0252.  Then release and you should see this:

Mario, LL does not define the x and y ranges.  x and y do that.  LL defines the list of lists that is used by the 'z' value.  I think that example 5 might not be worded properly, or in such a way that it isn't clear what is meant.  To prove this to yourself, execute the code, and then modify the x range and the y range accordingly to see what happens.  Here is an example below to illustrate this:

>restart:

>LL := [[0,0,0], [1,1,1], [2,2,2], [3,3,3]]:

>PLOT3D(GRID(1..10, 1..4, LL), AXESLABELS(x,y,z),ORIENTATION(135, 45), AXES(BOXED));

Can you supply more details as to what it is you are trying to do.  Are you plotting discrete data points and want to connect them with a "smooth" line, or are you plotting the frequency response of a filter.  Can you post your file or your commands so far, and data that goes with it.  From a functional standpoint, if your plot is of data (frequecny vs. magnitude for example), then it can certainly be "smoothed", but it really depends on what you want to do with the "smoothed" version of your plot.

Are you using the "Vista version of Maple 11 ", or Maple 11 loaded under Vista?  If you are using the non-Vista version, take a look here.

Here is a not so elegant way to do it.  I could not think of anything better at the time, but it works.

Take a look at the help files for the "profile" command and for the "time" command.  There are examples in each of the help pages.  Their have been previous threads covering these topics as well.  Search "profiling" at the top right hand side of the Mapleprimes page and you will see a list.
