From the help pages:

Important: The networks package has been deprecated.  Use the superseding commands GraphTheory[DrawGraph] and GraphTheory[DrawNetwork] instead.

See examples here.  Scroll 3/4 of the way down, and you will see an example with animation.  Change your code to use the new GraphTheory package, and use the animation example as a guide for your own problem.

I am using Maple input in the attached worksheet.  I do not see the problem that you are refering to.  Every time I run the worksheet, I get the same answer.  Notice in the last line, where zero (0) is replaced by zero.zero (0.0).  This forces a floating point approximation of the integral, to the default of 10 decimal places.

See ?exp for help with e^ and ?-> for help with defining functions.  It is good practice to include * as a multiplication sign in between your variables.

Look at the help page for ?Statistics[Fit] to get you started with fitting.  For function help, look at ?->.  You function would be written as p:=x->exp(x^4+0.5*a*x^2+b*x), and if a and b had values (for example, a=0.001 and b=0.001), and you wanted to know what p(3) was, you would enter p(3), and Maple would return a value (really large, for this example).  Is this what you are expecting?

See if you can transform your 2D plot to 3D and then animate. ?plottools[transform] for help and examples.

Yes.  In the help page for ?ErrorPlot you will see links:  The options argument can contain one or more of the options shown below. All unrecognized options will be passed to the ?plots[display] command. See ?plot[options] for details.

Attached file has an example using the ?display command to combine the plots.

See help page for ?Statistics[ErrorPlot], if you are using Maple.  errorbar() is a Matlab function.

See attached.  This has happened before, as reported by others.  I used a text editor to open the file and remove

some characters that looked like they did not belong there (8 total), saved the file, and opened it Maple.  It worked.  See if it looks like what you expect.

Using  Maple 15 Classic Interface:

restart: Digits:=20:

Sum(tan((1/180)*(4*j-3)*Pi), j = 1 .. 45):

evalf(%);

You should use ?add instead of ?sum for what you are trying to do.  ?sum is for symbolic summation.  See the help file for examples.

The multiplication is missing.  See attached.

restart:with(gfun):
erec :=  mu*Q(n + 1) - (n + mu)*Q(n) + n*Q(n - 1);
opoly := rectodiffeq(erec, Q(n), f(z));

Mean expects the data to be in an Array, according to the help file ?Mean.  Put square brackets around your data instead of parentheses.  See below.

restart: with(Statistics):

y1:=[76.0,75.9,76.1,75.9,76.0,76.1,76.1,76.0,75.9,76.0,76.0,75.9,75.9,75.9,76.0,75.8,76.0,76.0,75.9,75.9,75.9,75.9,75.9,75.9,75.9,76.0,75.9,76.0,76.0,76.0];

Mean(y1);

There seems to be an issue with special characters.  If you open your worksheet in a text editor (I'm using Notepad++) for this, you will notice 4 highlighted instances of VT1, VT2, VT3 and VT4.  By deleting the VT's, and saving, you can open the worksheet in Maple.
