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
