## Math

::: {#thm-line}

## Line

The equation of any straight line, called a linear equation, can be written as:

$$
y = mx + b
$$

:::

See @thm-line.


```{#lst-customers .sql lst-cap="Customers Query"}
SELECT * FROM Customers
```

Then we query the customers database (@lst-customers).

## Equations

Black-Scholes (@eq-black-scholes) is a mathematical model that seeks to explain the behavior of financial derivatives, most commonly options:

$$
\frac{\partial \mathrm C}{ \partial \mathrm t } + \frac{1}{2}\sigma^{2} \mathrm S^{2}
\frac{\partial^{2} \mathrm C}{\partial \mathrm C^2}
  + \mathrm r \mathrm S \frac{\partial \mathrm C}{\partial \mathrm S}\ =
  \mathrm r \mathrm C
