MathJax
Since I've been playing around with using Obsidian to organise myself, I tried out some of the MathJax support. These are some examples I've tinkered with.
Examples
An example of inline MathJax $\alpha, \beta, …, \omega$
$$\begin{matrix} 1 & x & x^2 \ 1 & y & y^2 \ 1 & z & z^2 \ \end{matrix}$$
$$ \begin{vmatrix} a & b \ c & d \ \end{vmatrix}=ad-bc $$
$$ \sum_{i=0}^n i^2 = \frac{(n^2+n)(2n+1)}{6} $$
$$ 10^{10} $$
$$ {x^y}^z $$
$$ x^{y^z} $$
$$ x_i^2 $$
$$ x_{i^2} $$
$$ \Biggl(\biggl(\Bigl(\bigl((x)\bigr)\Bigr)\biggr)\Biggr) $$
$$ \left(\frac{\sqrt x}{y^3}\right) $$
$$ \frac ab $$
$$ \frac{a+1}{b+1} $$
$$ x \approx y $$
$$ \sqrt[3]{4} $$
$$ \infty $$
$$ \aleph_0 $$
$$ \nabla $$
$$ \partial $$
$$ \Im $$
$$ \Re $$
