Eureka supports the rendering of mathematical formulas by using KaTeX.
You can type inline equation like $E=mc^2$.
And also displayed equation like:
\[ \int u \frac{dv}{dx}\, dx=uv-\int \frac{du}{dx}v\,dx \]
Matrix:
\[ \begin{pmatrix} a&b\\c&d \end{pmatrix} \quad
\begin{bmatrix} a&b\\c&d \end{bmatrix} \quad
\begin{Bmatrix} a&b\\c&d \end{Bmatrix} \quad
\begin{vmatrix} a&b\\c&d \end{vmatrix} \]
Aligned equation:
\[\begin{aligned}
x ={}& a+b+c+{} \\
&d+e+f+g
\end{aligned}\]
And many other kinds of formulas.
