This blog post demonstrates how to use LaTeX in Hugo for various types of equations and theories, including mathematics, physics, and chemistry.

### Mathematical Equations

#### Quadratic Formula

The quadratic formula is used to solve quadratic equations and is given by: $ ( x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} ) $

#### Pythagorean Theorem

The Pythagorean theorem relates the lengths of the sides of a right triangle: $ ( a^2 + b^2 = c^2 ) $

#### Euler’s Identity

Euler’s identity is a famous equation in mathematics: $ ( e^{i\pi} + 1 = 0 ) $

### Physics Equations

#### Newton’s Second Law

Newton’s second law states that the force acting on an object is equal to its mass times its acceleration: $ ( F = ma ) $

#### Einstein’s Mass-Energy Equivalence

Einstein’s mass-energy equivalence formula is one of the most famous equations in physics: $ ( E = mc^2 ) $

#### Gravitational Force

The gravitational force between two masses is given by Newton’s law of gravitation: $ ( F = G \frac{m_1 m_2}{r^2} ) $

### Chemistry Equations

#### Water Molecule

The chemical formula for water is: $ \text{H}_2\text{O} $

#### Ideal Gas Law

The ideal gas law relates the pressure, volume, and temperature of an ideal gas: $ ( PV = nRT ) $

#### Chemical Reaction

An example of a chemical reaction, the combustion of methane: $ \text{CH}_4 + 2\text{O}_2 \rightarrow \text{CO}_2 + 2\text{H}_2\text{O} $

### Conclusion

Using LaTeX in Hugo with the configured delimiters allows for the clear and accurate representation of complex equations in blog posts. This is particularly useful for content related to mathematics, physics, and chemistry.

## Configuration

To enable LaTeX in Hugo, add the following configuration to your `config.toml`

file:

```
[markup]
[markup.goldmark]
[markup.goldmark.extensions]
[markup.goldmark.extensions.passthrough]
[markup.goldmark.extensions.passthrough.delimiters]
block = [['@@', '@@']]
inline = [['@', '@']]
```
