comment Problems with Solve
@m_goldberg that is what I did first. Broke that clooped up code into separate cells to see if each work. The problem is Solve can't solve the equations even with Real option. I do not know why people do not break code into separate pieces and run each in sequence any more like we used to do in the good old days. Wrapping functions inside other functions might make things look cool, but it makes debugging very hard.

comment Problems with Solve
Solve::nsmet : "This system cannot be solved with the methods available to Solve." You can't expect magic to happen, if when using Mathematica. Some equations can't be analytically solved.

comment Why are functions called first-class objects in Mathematica?
The f = 9; f[x_]:=x^2 error since now the second line reads as 9[x_]:=x^2

comment Geometric Transformation not working - degenerate points?
This error message is not documented anywhere in the help. So only suggestion is to contact support@wolfram.com, someone with access to the source code internally will be able to know. It could be simply that it does not support larger than 3 dimensions space.

comment Parallel kernel and front end
from help, it says: generates a monitor cell that shows the continually updated current value...In a notebook, the monitor cell normally appears directly after the cell in which Monitor[expr,mon] is evaluated so clearly Monitor requires a frontend. Can't be used in script/batch.

comment How to find all symbols in an expression and perform an operation on them?
.. just saw eldo post after hitting post.... This is a little different may be. In Mathematica, we should always try to come up with 10 different ways to solve something :)

comment Formatting Fortran complex number output for use in Mathematica
How did you use "Import"? Please provide example of the data in the file, and the command you used. M can import Fortran data reference.wolfram.com/mathematica/tutorial/…

comment Formatting Fortran complex number output for use in Mathematica
How did you "get" the array from Fortran to look like this in first place and have it land inside Mathematica? Was the data in file and you imported it into Mathematica?

comment What's a non-trivial Mathematica program involving conscious choice of stack vs. queue data structure?
I also do not think Mathematica is the right choice for computer science algorithms course, since it is a high level language. Same as Matlab is not a good choice, and neither is Maple. We used Pascal for this at school where one can 'see' things. In higher level languages, the need to implement such data structures is not needed as much as in low level and system programming.

comment What's a non-trivial Mathematica program involving conscious choice of stack vs. queue data structure?
M is a high level language (4th generation if you will), so most of the time, you do not need to implement these data structures since they are not needed, Mathematica commands already there to do pretty much anything you want. But if you want to implement them you can. Here is a link that shows how to library.wolfram.com/conferences/devconf99/lichtblau

fyi, this is pretty much the same answer given by jkuczm above.

is c>0? if so, int = Assuming[c > 0, Integrate[(2 c - (r^2) Exp[-I 1.4746])^(0.5), {r, 0, 31.7576}]] gives the answer in Hypergeometric2F1

This could be a bug, as help says it is supposed to combine them.

comment How to use Assumptions in a Series Expansion
@MichaelE2 fyi, Wolfram alpha was smart enough to parse part of this command even in Latex! It gave back Series Sqrt, ok not exactly the full command, but very impressive none-the-less !Mathematica graphics may be in the future with more AI it will be able to process full latex input as well.

comment How avoid white space and tags in CDF on web page
the unwanted space can be easily taken care off with correct width and height values in your HTML command to load the CDF. Screen shot !Mathematica graphics I just used <embed src="Untitled.cdf" width="400" height="400"/> and the yellow color is because your set the page color to yellow. I just removed that. In V9, there is an export CDF in the menu, selecting export standalone CDF, you should get the same result as I have.

comment Maximum and mean of a multi-variate function over a restricted lattice
Please do not use UpperCaseFirstLetter, can be confusing since M commands all start with UpperCase. Using lowerCaseFirstLetter is recommended in Mathematica.

comment How avoid white space and tags in CDF on web page
I can't reproduce this. I do not know how you exported this. Here is screen shot on my browser for a your notebook that I exported as CDF and loaded in HTML !Mathematica graphics as you can see the brackets are not there. Did you save the CDF as standalone? I am using V 9.01 on windows, firefox. May be this behaves differently in V8. If you have V9 maybe you can try exporting it from V9 instead.

fyi, cross posted community.wolfram.com/groups/-/m/t/283665?p_p_auth=kD3FBYSv please mention this in your question on both sites so not to waste people time duplicating answers and efforts.
