You can also have things inline like \alpha or
This is how it looks like :).
Does it work a bit better like this? \begin{equation} a=2 \end{equation}
This is an equation: \begin{equation} y+2 = 3 \end{equation}
This is a system of equations: \begin{align*} x^2+y^2 & = 2 \ \sin(y) & = 0.2 \end{align*}
This is Euler's formula: \begin{eqnarray*} e^{i\pi} + 1 & = & 0. \end{eqnarray*}
Katex only syntax $$ \begin{aligned} x^2+y^2 & = 2 \ \sin(y) & = 0.5 \ x &= y \end{aligned} $$
\begin{align} 1+2 =3 \end{align}
