TexPaste: Math Pastebin with LaTeX

Insert inline Insert block

${{symbol.code}}$

TexPaste provides an online LaTex editor that could be used to facilitate sharing of math notes.

Wrap inline equation like this: $ x_n = \sqrt{a + b} $ and you can continue writing on the same line.

For simplicity, you can also use double/single dollar signs for block/inline, like this: $ x - 1 = 0 $, or:
$$ a^n + b^n = c^n $$
(this is the old TeX syntax, LaTeX support it though).

A more complicated equation should be rendered in block:
\[
i\hbar\frac{\partial \psi}{\partial t}
= \frac{-\hbar^2}{2m} \left(
\frac{\partial^2}{\partial x^2}
+ \frac{\partial^2}{\partial y^2}
+ \frac{\partial^2}{\partial z^2}
\right) \psi + V \psi.
\]

Some features supported by this editor are listed below. Here is an example of an aligned equation:
\[
\begin{align*}
1+\tan^2 x & = 1+ \frac{\sin^2 x}{\cos^2 x} \\
&= \frac{\sin^2 x +\cos^2 x }{\cos^2 x} \\
&= \frac{1}{\cos^2 x} \\
&= \sec^2 x.
\end{align*}
\]
And this is an example of a piecewise function:
\[
f(x) =
\begin{cases}
1                           & \text {if $x=1$} \\
1+x+x^2+\cdots   & \text{if $x = 0$} \\
\dfrac{1}{1-x}        & \text{if $x = -1$} \\
\text{undefined}    & \text{otherwise} \\
\end{cases}
\]
Matrix is another commonly used math object:
\[
\begin{pmatrix}
a_{1,1} & a_{1,2} & \cdots & a_{1,n} \\
a_{2,1} & a_{2,2} & \cdots & a_{2,n} \\
\vdots  & \vdots  & \ddots & \vdots  \\
a_{m,1} & a_{m,2} & \cdots & a_{m,n}
\end{pmatrix}
\]
To create tables, you can use 'array' environment as followed:
\[
\begin{array}{ccc}
\text{time} & 0 &  t_1\\
\hline
\text{long } F_1 \text{-contract} & 0 & S_1-F_1 \\
\text{short } F_2 \text{-contract} & 0 & (F_1-F_{1,2})e^{-r(t_2-t_1)} \\
\hline
\text{total} & 0 & (F_1-F_{1,2})e^{-r(t_2-t_1)} +S_1-F_1
\end{array}
\]
