    Ah! I read it as \(\lim_{n \rightarrow \infty } \left(2-\ln (n) \right)\)

    It makes sense when you're sober!

    As I understand

    (Infinity)a -(Infinity)b = o or any other number positive or negetive no. depending on the value of (Infinity)a and (Infinity)b.

    Just testing. I will delete this if I can:

    \(f = \sqrt(1 - \frac{2GM}{c^2 r}) \)
    \(\frac{\partial f}{\partial r} = \frac{GM}{c^2 r^2 f}\)

    No need to delete. This thread is OK to use for tex tests, demos, tricks, etc.

    How about this, as a simple way to display matrices:

    enclose in tex tags the following

    \begin{pmatrix}1 & 0\\
    0 & 1
    \end{pmatrix}

    yielding \(\begin{pmatrix}1 & 0\\ 0 & 1 \end{pmatrix} \).

    If you want more space between the rows, just chuck in a few more \\,

    like \begin{pmatrix}1 & 0\\
    \\
    \\
    \\
    0 & 1
    \end{pmatrix} which delivers \(\begin{pmatrix}1 & 0\\ \\ \\ \\ 0 & 1 \end{pmatrix}\)

    Here are a couple of bugs/omissions I detected with this implementation of LaTex.

    The congruence glyph "\cong" is not supported;

    the proper subset glyph "\subsetne" is not supported;

    Lower case fraktur font is not supported;

    enclosed text "\text{blah blah}" is not supported;

    In-line math, as "[itex]", "\textstyle{blah}" is not supported, neither is the command "\tfrac" for in-line fractions

    the package xy-pic is not included (agreed, this would be a great luxury, but great, nonetheless, and not too hard to implement, I believe)

    To prove Absane's relation, a clever use of power series does the trick.

    Hey folks! I've been using this for a while. I highly recommend it, it's really cool!

    \(\pi=3+\frac{1}{6+\frac{9}{6+\frac{25}{6+\frac{49}{6+\frac{81}{6+\frac{121}{6+\frac{169}{6+\frac{225}{\ddots}}}}}}}}\)

    Is there a simple way to make the size not reduce as the fractions go on?

    Try this:
    \( \pi = 3+\frac{1}{ \large 6+\frac{9}{ \large 6+\frac{25}{ \large 6+\frac{49}{ \large 6+\frac{81}{ \large 6+\frac{121}{ \large 6+\frac{169}{ \large 6+\frac{225}{ \large \ddots } } } } } } } } \)
    Code:
    [tex-]
    \large
    \pi = 
    3+\frac{1}{\large 
      6+\frac{9}{\large 
        6+\frac{25}{\large 
          6+\frac{49}{\large 
            6+\frac{81}{\large 
              6+\frac{121}{\large 
                6+\frac{169}{\large 
                  6+\frac{225}{\large 
                    \ddots
                  }
                }
              }
            }
          }
        }
      }
    }
    [/tex]

    Thanks. I see it makes no difference how you lay out your code, only the \large function makes a difference.

    \(\large1+\frac{1}{\large1+\frac{2}{\large1+\frac{3}{\large1+\frac{4}{\large\ddots}}}}\)

    Code:
    \large1+\frac{1}{\large1+\frac{2}{\large1+\frac{3}{\large1+\frac{4}{\large\ddots}}}}
