LaTeX Symbols FAQ
How do I use Greek uppercase vs lowercase letters in LaTeX?▼
In LaTeX, lowercase Greek letters use lowercase commands (e.g., \alpha, \beta, \theta). Uppercase Greek letters capitalize the first letter of the command (e.g., \Gamma, \Delta, \Theta, \Omega).
Which symbols require the amsmath or amssymb packages?▼
Symbols like \iint, \iiint, \implies, and \dddot require \usepackage{amsmath}. Blackboard bold letters (\mathbb{R}, \mathbb{N}), special empty sets (\varnothing), and advanced arrows require \usepackage{amssymb}. Each symbol card clearly displays its package badge.
How do I send a symbol to the equation workspace?▼
Click the "Editor ↗" link on any symbol card. LaTeXTool will immediately load the symbol into the homepage equation editor workspace above the fold.
Do all LaTeX symbols require math mode?▼
Yes, mathematical symbols, Greek letters, and operators must be enclosed in dollar signs for inline math ($...$) or in display math environments (\[ ... \] or equation blocks).
