Therefore symbol in LaTeX

There is no therefore symbol in the default LaTeX packages. There are (at least) two ways of getting the symbol:

The package amssymb contains the \therefore symbol definition. To use, do something like:

\usepackage{amssymb}
...
$\therefore 1 \neq 2$

Alternatively, you can create your own therefore definition:

\def\therefore{
\leavevmode
\lower0.1ex\hbox{$\bullet$}
\kern-0.2em\raise0.7ex\hbox{$\bullet$}
\kern-0.2em\lower0.2ex\hbox{$\bullet$}
\thinspace}

The amssymb therefore has tiny dots, whereas the definition above has large dots. Take your pick.

    I muddled around with \cdot in the place of \bullet and got a result that I like. If anybody else stumbles across this article, this is what I used:

    \def\therefore{\boldsymbol{\text{ }
    \leavevmode
    \lower0.4ex\hbox{$\cdot$}
    \kern-.5em\raise0.7ex\hbox{$\cdot$}
    \kern-0.55em\lower0.4ex\hbox{$\cdot$}
    \thinspace\text{ }}}

    Thanks much. Helped me out of a minor jam there…

    I have a far more intractable problem: Google Docs. This is how I manage: $.^..$

  4. Taffie says:

    \usepackage{amssymb}
    \usepackage{amsmath}

    $\therefore$ some text here

    Produces the output desired, with thinner dots. The $ around \therefore denotes that it will be using a math function, similar with $\Theta$

    I’m the beginner and I have problems in this, solved it with your help. Thanks
