Displaying equations using Tex

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)
 
Absane, could you explain that constant? I can't grasp it! Surely as x approaches inf. then ln(x) also approaches something high too?

To prove Absane's relation, a clever use of power series does the trick. ;)
 
$$\frac {1}{\frac{2}{\frac{3}{4}}} = 0.041 \overline{6}$$

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

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
              }
            }
          }
        }
      }
    }
  }
}

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}}}}
