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.

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.

Block Math

For standalone equations that deserve their own line, use a math block. There are several ways to insert one:

• Slash command: Type / and search for "Math Block"
• Keyboard shortcut: Cmd+Shift+M (Mac) or Ctrl+Shift+M (Windows/Linux)
• Paste: Paste text wrapped in double dollar signs ($$...$$) and it will automatically convert to a math block

Once inserted, type your LaTeX directly into the block. The equation renders in display mode, centered on its own line—great for larger expressions like:

$$
\int_0^\infty e^{-x^2} dx = \frac{\sqrt{\pi}}{2}
$$

Editing a math block:

• Double-click the rendered equation to edit it
• Press Enter when the block is selected to enter edit mode
• Press Shift+Enter or Escape to finish editing
• Empty math blocks are automatically removed when you exit edit mode

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 → ≈
