📝 What is LaTeX?

LaTeX is a typesetting system widely used for producing scientific and mathematical documents. It excels at rendering complex mathematical formulas, equations, and technical notation with professional-quality output. LaTeX uses markup commands to describe the structure and formatting of equations, making it the standard for academic papers, textbooks, and scientific publications worldwide.

💡 LaTeX Tips & Tricks

•Use \frac{a}{b} for fractions instead of a/b for better display
•Wrap subscripts and superscripts in braces: x_{10} or e^{2\pi i}
•Use \left( and \right) for auto-sizing parentheses
•Common functions like sin, cos, log should use backslash: \sin, \cos, \log
•Use \text{} to include regular text within equations

Frequently Asked Questions

What LaTeX syntax is supported?

This editor supports most standard LaTeX math commands including fractions, roots, summations, integrals, matrices, Greek letters, and more. It uses KaTeX for rendering, which supports over 400 LaTeX functions.

Can I use this for complex equations?

Yes! You can create complex multi-line equations, matrices, systems of equations, and nested expressions. Use environments like \begin{align} or \begin{matrix} for advanced layouts.

How do I copy equations to other applications?

Click 'Copy LaTeX' to copy the raw LaTeX code (works in most LaTeX-compatible editors), or 'Copy MathML' for applications like Microsoft Word that support MathML import.

Is my data saved or stored?

Equation history is stored only in your browser's local storage. We don't send or store your equations on any server. Your privacy is fully protected.

What's the difference between inline and display mode?

Inline mode renders equations within text (smaller, fits on a line), while display mode renders equations as centered, larger blocks suitable for standalone formulas.
