Thank you MIF, I will delete it once I have printed out and handed in.

I will download a pc program and learn to latex with the software, but it may take some time, so I came up with the idea of using the math command here temperarily.

Excuse me.

If you need any help with doing so, just ask. MikTex is by far the easiest to use in my experience.

That's fine.

Ricky: I might try MikTex myself

Al right, just leave the miktex homepage here

http://miktex.org

So it must be a freeware, wow!

After downloading and installing miktex, you will probably want an IDE. TexnicCenter was the one I used. Wasn't great, but it did the job.

Edited to add: I always use freeware when there is the option to. Same goes with open source.

Thank you Ricky! I will try them.

If you want, you can use the Preview command to show the LaTeX, then copy the image to wherever you want it, and never have to actually post.

Why did the vector cross the road?

It wanted to be normal.

I don't know why one has to install two latex softwares for typing Latex.

This is actually something worth discussing in the Coder's Corner. A recent trend in software design is to break a piece of software down into divisible pieces. This does a number of things. First, each piece is smaller than the whole and much easier to develop. But more importantly, it allows for the user to choose between different pieces. You can switch your front end for latex (the user interface) without having to change the program used to compile and produce the pdfs. Latex is a beast, I could only imagine trying to code it. On the other hand, user interfaces are relatively easy. So instead of forcing everyone to program both, people can all just use MikTex and make the user interface over top of it.

Texmaker might be one good example of splitting a task into a subtask too small.

It looks pretty, much more pretty than Microsoft Word.

It looks nice, every maths symbol ready to use.

But where the hell can I get a bunch of Latex maths symbols out instead of a string of sheer commands like

" \int e^{x}\dx=e^{x}"

????????!!!!!!!!

I strongly disagree. Writing a Tex compiler is a very intensive and difficult process, especially making sure that it conforms will all the Tex and Latex (let alone other types of Tex like BibTex) standards. Hell, there is a 120 page document that simply lists math commands. It is a huge library.

I'm not certain what you mean. Are you saying you have a Latex document and can't figure out how to compile it into a pdf or dvi? Or is it something else?

It always tells me

"Cannot find file name"

whenever I try to transform codes into symbol format.

even 1+1=2 doesn't work

Alright. I got it. It simply cannot compile it when it is not formally saved, where "formally saved" means saved with a name other than "untitled".
