Quotes

This is a blockquote.

Code

Inline code: code

Code block:

def hello_world():
    print("Hello, world!")

You can copy straight from code blocks by clicking the button on the right Very useful if you need to copy commands or code quickly - like the following Shell commands

@reboot ( sleep 15 ; /usr/bin/socat -d -d pty,raw,echo=0 pty,raw,echo=0 )
@reboot ( sleep 20 ; /usr/bin/socat -v udp4-datagram:192.168.2.86:3000 open:/dev/pts/1,raw,nonblock,waitlock=/tmp/s0.locak,echo=0,b115200,crnl )

LaTeX Rendering Example

Inline Math

This is an example of inline math: $(E=mc^2)$. You can use single dollar signs for inline math.

Display Math

For display math, use double dollar signs:

$$ \int_{0}^{\infty} e^{-x^2} ,dx = \frac{\sqrt{\pi}}{2} $$

Mathematical Symbols

Some mathematical symbols:

  • $(\alpha, \beta, \gamma)$
  • $(\sum_{i=1}^{n} i^2)$
  • $(\frac{1}{2})$
  • $(\sqrt{2})$
  • $(\Rightarrow)$

Equations with Numbering

$$a^2 + b^2 = c^2$$

This is a numbered equation.

Matrices

Matrices:

$$\begin{bmatrix} 1 & 2 \\ 3 & 4 \end{bmatrix} $$

Greek Letters

Some Greek letters: $$(\alpha, \beta, \gamma, \delta, \epsilon)$$

Fractions

A fraction: $$(\frac{3}{4})$$

Callouts

These can help draw emphasis on information (and look pretty too)

[!info] > Here's a callout block. > It supports Markdown, [[Welcome|note links]], and embedded files > ![[Pasted image 20240123163530.png]]

[!tip] Callouts can have custom titles > Like this one.

[!faq]- Are callouts foldable? Yes! In a foldable callout, the contents are hidden when the callout is collapsed.

[!question] Can callouts be nested?

[!todo] Yes!, they can.

[!example] You can even use multiple layers of nesting.

[!info] You can even put equations in callouts Black-Scholes Option Pricing Model Non-dividend paying stock

$$C=S^{x}\times N(d_{1})-PV(K)\times N(d_{2})$$

$$S^{x}=S-PV(Div)$$ $$d_{1}=\frac{ln(\frac{S^{x}}{PV(K)})}{\sigma \sqrt{T}}+\frac{\sigma \sqrt{T}}{2}$$

$$d_{2}=d_{1}-\sigma \sqrt{T}$$

There's many different kinds of callouts - see https://help.obsidian.md/Editing+and+formatting/Callouts#Supported+types for examples
