# LaTeX / Mathematical Equations
## Inline equation
Einstein's formula: = $mc^2$
```latex
Einstein's formula: = $mc^2$
```
## Block equation
$
\int_{-\infty}^{\infty} e^{-x^2} dx = \sqrt{\pi}
$
```latex
$

$
```
## Matrix
$
\begin{pmatrix}
a & b \\
c & d
\end{pmatrix}
$
```latex
$
\begin{pmatrix}
a & b \\
c & d
\end{pmatrix}
$
```
## Other Notation
$
\displaystyle\sum_{k=3}^5 k^2=3^2 + 4^2 + 5^2 =50
$
```latex

```
$3\neq4$
```latex

```
$\sin(0.01) \approx 0.01$
```latex
$\sin(0.01) \approx 0.01$
```
$\lim_{x\to\infty} f(x)$
```latex

```
$
f(x) = \sum_{i=0}^{n} \frac{a_i}{1+x}
$
```latex
$
f(x) = \sum_{i=0}^{n} \frac{a_i}{1+x}
$
```
... it just keeps going.
There's an entire page that shows how to input different formulae in LaTeX, meaning all can be shown as such within Markdown.
