# README

Some collection of code and code snippets to look up quickly since I frequently use them [gitbook.io Link](https://martinfeineis.gitbook.io/newlib/)\

{% hint style="warning" %}
Gitbooks uses `{% hint %}` [blocks](https://gitbook.com/docs/creating-content/blocks/hint#example-of-a-hint) to render blockquotes
{% endhint %}

> \[!TIP] Markdown uses `>` indentations [see](https://www.markdownlang.com/basic/blockquotes.html#_3-tip-message)\
> :atm: [github](https://gist.github.com/rxaviers/7360908) markdown also support emojis ✅

### Math Formulas

Gitbook [Docs](https://gitbook.com/docs/creating-content/blocks/math-and-tex) with [KatTeX](https://katex.org/docs/supported.html) typesetting library **Inline equation**

[Euler's Identity](https://en.wikipedia.org/wiki/Euler's_identity): $$e^{ i \pi } + 1 = 0$$

**Math block** Maxwell's Equations\\

$$
\nabla \cdot E = \frac{\rho}{\epsilon\_0} \\
\nabla \cdot B = 0 \\
\nabla \times E = - \frac{1}{c} \frac{\partial B}{\partial t} \\
\nabla \times B = \mu\_0 \big( J + \epsilon\_0 \frac{\partial E}{\partial t} \big)
$$
