Examples & Syntax

Input	Rendered
$E=mc^2$	$E=mc^2$
$\hat{y} = \sigma(w \cdot x + b)$	$\hat{y} = \sigma(w \cdot x + b)$
$\mathbf{X}^T \mathbf{X} \mathbf{w} = \mathbf{X}^T \mathbf{y}$	$\mathbf{X}^T \mathbf{X} \mathbf{w} = \mathbf{X}^T \mathbf{y}$
$\bar{x} = \frac{\sum x_i}{n}$	$\bar{x} = \frac{\sum x_i}{n}$

If you're incorporating LaTeX within text paragraphs, use single dollar signs for inline math, like $E=mc^2$, ($E=mc^2$) and double dollar signs for displayed equations, like $$\hat{y} = \sigma(w \cdot x + b)$$ to display it like this:

$$\hat{y} = \sigma(w \cdot x + b)$$
