Below is the mathematical typography that is used on this site.

A non-bold standard letter is used to denote a basic scalar:

$c = 3e8$

Bold font and an arrow is used to denote a vector:

$\b{\vec{v}} = \begin{bmatrix}1\\2\\3\end{bmatrix}$

Bold font and a hat is used to denote a unit vector:

$\b{\hat{x}} = \begin{bmatrix}1\\0\\0\end{bmatrix}$

A bold capital letter is used to denote a matrix or tensor:

$\b{B} = \begin{bmatrix}1&2&3\\4&5&6\\7&8&9\end{bmatrix}$

A bold lower-case letter is used to denote imaginary component(s) (in things such as complex numbers and quaternions).

$c = a + b\mathbf{i}$

$q = a + b\mathbf{i} + c\mathbf{j} + d\mathbf{k}$

A bar is used to indicate a conjugate:

$\bar{x}$

The “triangle equals” is used to denote “is defined by”:

$F \triangleq ma$

The Fourier Transform is denoted with $\mathcal{F}$ .

Belongs to uses the \in symbol from Latex (e.g. $x$ belongs to the set of real numbers):

$x \in \mathbb{R}$
