LaTeX Math

LaTeX offers the most comprehensive math markup of any software.

LaTeX Math

Usage

There are two ways to use math markup: inline math mode and display math mode.

An example of the inline style is \(a + bx = y\), whereas an example of display style is:

\[ a + bx = y \]

Math Fonts

For curly letters, as in what is used for sigma algebras:

\mathcal{O}

$mathcal.svg$

For blackboard letters, as in what is used for matrices:

\mathbb{X}

$mathbb.svg$

Markup

Many symbols are available by name, or some contraction of the name.

Syntax	Symbol
`\partial`	∂
`\nabla`	∇
`\infty`	∞
`\varepsilon`	ε
`\varphi`	φ
`\forall`	∀
`\times`	×
`\cdot`	⋅
`\in`	∈
`\subset`	⊂
`\cap`	∩
`\cup`	∪
`\neq`	≠
`\pm`	±
`\lt`	<
`\leq`	≤
`\gt`	>
`\geq`	≥
`\approx`	≈
`\perp`	⊥

Greek letters are available by name. Note that by default the lowercase letter is returned; capitalizing the name returns the uppercase letter. For example, \Phi gives Φ while \phi gives ϕ.

Many function notations are also available.

Syntax	Appearance
`\frac{1}{2}`	$frac.svg$
`\sum_{i=1}^{N}`	$sum1.svg$
`\sum\nolimits_{i}`	$sum2.svg$
`\prod_{i=1}^{N}`	$prod.svg$
`\lim_{x\to\infty}`	$lim1.svg$
`\lim\nolimits_{x\to\infty}`	$lim2.svg$
`\int_a^b`
`f\vert_a`	$eval.svg$

There are several sizes of parentheses, braces, and bars available. As a demonstration:

\Big( \big( (x + 1) + 1 \big) + 1 \Big)

\Big[ \big[ \left[ x + 1 \right] + 1 \big] + 1 \Big]

\Big| \big| |a| - |b| \big| - |c| \Big|
