General ⇒ therefore charachter (simple)

[deadrabit]

heyya, i'm trying to get the therefore logic symbol in displaymath mode, ive searched around a bit (very difficult to search for), and all the obvious commands (\therefore etc...) dont seem to produce it, also its not listed in the symbol menus in texnic centre.



whats the command?

thanks
D.R.

Hi,

have a look at the The Comprehensive LaTeX Symbol List, that's a huge list of symbols available for LaTeX.

Include the amsmath package and use the \therefore command.

Include the amsmath package and use the \therefore command.

That won't work.

Include the amssymb package (not amsmath) and use the \therefore command (of course, you may also include amsmath, but that's up to you).

Also note that \therefore is a relation symbol, and so its spacing may seem funny (i.e., it may have too much space in front of it). If so, force it to be what you want it to be. For example

Code: Select all

\mathord{\therefore}\,

will produce a \therefore at the beginning of the line (no space) with a small space after it. You could do...

Code: Select all

\newcommand\thfore{\mathord{\therefore}\,}

and then use \thfore.

@localghost: The TUG/CTAN community is asking people to use the new CTAN URLs, like:

• http://ctan.org/pkg/amssymb

Also, there's an argument to encouraging people using mathtools instead of amsmath.

That's definetely right. I wasn't aware of the fact that the kpfonts package also seems to load amssymb so I did the wrong conclusion. I could neither find it in the *File List* of the log file when compiling my document nor any hints in the documentation.

There are no hints about that on the sides of CTAN. I'd appreciate if you could point that out (not only to me).

From a message on CTT (comp.text.tex) from Jim Hefferon (note: he's quoting Will Robertson):

Yes; the second just becomes the first. I'm glad you like it. I won
a REST book at the San Diego meeting.
