Math Formula Markdown

Math Formula Markdown

Markdown is a lightweight markup language used to format text. One of its powerful extensions is the ability to include mathematical formulas, which is particularly useful for academic and technical writing. Math formulas in Markdown can be written using LaTeX syntax, which is widely used for typesetting mathematical and scientific documents.

Basic Syntax

To write math formulas in Markdown, you can use dollar signs $ to delimit inline math and double dollar signs $$ for display math.

• Inline Math: Enclosed by single dollar signs $...$.
• Display Math: Enclosed by double dollar signs $$...$$.

Examples

Inline Math

Inline math is used for formulas that are part of a paragraph. For example:

Markdown: The quadratic formula is given by $x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$.

Rendered: The quadratic formula is given by \(x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}\).

Display Math

Display math is used for standalone formulas that are centered and more prominent. For example:

Markdown:

$$
E = mc^2
$$

Rendered:

$$ E = mc^2 $$

Common Mathematical Symbols and Notations

Here are some common mathematical symbols and how to write them in Markdown using LaTeX syntax:

Fractions

Markdown: $\frac{a}{b}$

Rendered: \(\frac{a}{b}\)

Exponents and Indices

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

Rendered: \(a^2 + b^2 = c^2\)

Greek Letters

Markdown: $\alpha, \beta, \gamma$

Rendered: \(\alpha, \beta, \gamma\)

Integrals

Markdown: $\int_a^b f(x) \, dx$

Rendered: \(\int_a^b f(x) \, dx\)

Summations

Markdown: $\sum_{i=1}^n i$

Rendered: \(\sum_{i=1}^n i\)

Complex Equations

For more complex equations, you can combine multiple LaTeX commands. For example:

Markdown:

$$
\begin{align}
a &= b + c \\
d &= e + f
\end{align}
$$

Rendered:

$$ \begin{align} a &= b + c \\ d &= e + f \end{align} $$

Using MathJax

Many Markdown processors, including Jupyter notebooks, GitHub, and various static site generators, support LaTeX for rendering math. They often use MathJax, a JavaScript display engine, to render these formulas.

To include MathJax in a Markdown document for local or web usage, you can include the following script in your HTML:

<script src="https://polyfill.io/v3/polyfill.min.js?features=es6"></script>
<script id="MathJax-script" async src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-mml-chtml.js"></script>

Conclusion

Using Markdown to write mathematical formulas can significantly enhance the readability and professionalism of technical documents. By leveraging LaTeX syntax within Markdown, you can create complex equations and notations with ease. Whether you're writing a research paper, creating educational content, or documenting technical processes, mastering math formulas in Markdown is a valuable skill.
