LaTeX

Octarine supports LaTeX for mathematical notation and scientific formulas, rendering them beautifully inline with your text. Perfect for academic writing, technical documentation, and mathematical notes.

By default latex rendering is turned OFF since it's perf intensive. To turn on, head over to Settings -> Editor and toggle Render Math Equations on.

Inline Math

To include math within a line of text, just wrap your formula in single dollar signs. For example, $E = mc^2$ renders as Einstein's famous equation inline. More complex expressions work too—something like $\\int_0^\\infty e^{-x^2} dx = \\frac{\\sqrt{\\pi}}{2}$ will render beautifully right alongside your writing.

Quick Reference

Here are some of the most commonly used LaTeX symbols and how to write them:

Basic notation:

Superscript: x^2 → x²
Subscript: x_1 → x₁
Fractions: \frac{a}{b} → a/b
Square root: \sqrt{x} → √x
Sum: \sum_{i=1}^n → Σ
Integral: \int_a^b → ∫

Greek letters:

\alpha, \beta, \gamma → α, β, γ
\Delta, \Omega → Δ, Ω
\pi, \theta, \phi → π, θ, φ

Mathematical operations:

\times → ×
\div → ÷
\pm → ±
\leq, \geq → ≤, ≥
\neq → ≠
\approx → ≈
