Write beautiful LaTeX equations

OryanApp renders equations with KaTeX, so your math looks typeset — not like a screenshot. You write standard LaTeX and it renders live as you type.

Insert an equation

1. 1
   In the left panel’s Elements tab, under Equation (LaTeX), click Insert equation.
2. 2
   Double-click the equation on the canvas to edit its LaTeX source. It re-renders as you type.

LaTeX basics

Some syntax you’ll reach for constantly:

x^2            % superscript
x_i            % subscript
\frac{a}{b}    % fraction
\sqrt{x}       % square root
\sum_{i=1}^{n} % summation
\alpha \beta   % Greek letters
\hat{x} \vec{v}

Multi-line and aligned math work as you’d expect:

\begin{aligned}
  \nabla \cdot \mathbf{E} &= \frac{\rho}{\varepsilon_0} \\
  \nabla \cdot \mathbf{B} &= 0
\end{aligned}

Sizing and alignment

Resize an equation like any element by dragging its handles — the math scales with the box. In the right-hand properties panel you can adjust the equation’s box and alignment so it sits exactly where you want relative to the text around it.

Spotlight a term

Want to draw attention to one part of an equation during a talk? Select a portion of the LaTeX source in the properties panel and add a spotlight to it — OryanApp highlights just that term in the rendered equation.
