Logseq/Math

• Logseq #Math Rendering

  • My Note I have a rulesync/command in this repo for doing cleanup of logseq math in a #Markdown page: .rulesync/commands/logseq-cleanup-math.md
  • Logseq supports LaTeX math rendering using KaTeX — both inline and block math. Here's how to use it:

    • 🧮 Inline Math

      • Wrap your LaTeX expression in single dollar signs:
        • This is inline math: Inline: E = mc^2
      • Example:

        • This is inline math: $E = mc^2$

    • 📐 Block Math

      • Wrap your expression in double dollar signs on separate lines (not inline):
        • \int_0^\infty e^{-x^2} dx = \frac{\sqrt{\pi}}{2}
      • Example format:

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

      • Important: The $$ must be on separate lines, not inline like $$formula$$. This ensures proper rendering in Logseq.

    • ⚙️ Optional Settings

      • If math doesn't render:
        • Open Settings → Editor.
        • Ensure "Enable math rendering (KaTeX)" is toggled on.
        • Reload Logseq (Cmd/Ctrl+R).

    • ✅ Tip

      • You can mix math and Markdown freely — KaTeX supports most LaTeX commands except for those that rely on packages not supported by KaTeX (e.g. \usepackage).
