LaTeX Rendering Guide

Evox Exam supports LaTeX for rendering complex mathematical expressions. Use the delimiters below to include math in your questions, answers, and descriptions.

How it Works

We use KaTeX to provide high-quality mathematical typography. When you wrap text in specific delimiters, our system automatically converts the LaTeX code into beautiful formulas. This works anywhere you can enter text, including question titles and answer choices.

Delimiters

DelimiterTypeResult
\( ... \)InlineRenders within the sentence
$$ ... $$BlockRenders on a new line, centered
\[ ... \]BlockRenders on a new line, centered

Examples

Inline Math

Use inline delimiters to include symbols or small equations directly in your text.

What you type:

The area of a circle is defined by \( A = \pi r^2 \), where \( r \) is the radius.

How it looks:

The area of a circle is defined by A=πr2 A = \pi r^2 A=πr2, where r r r is the radius.
Block Math

Use block delimiters ($$ ... $$ or \[ ... \]) for larger equations that should stand out on their own line.

What you type:

The fundamental theorem of calculus states: $$ \int_a^b f(x) \, dx = F(b) - F(a) $$

How it looks:

The fundamental theorem of calculus states:
∫abf(x) dx=F(b)−F(a) \int_a^b f(x) \, dx = F(b) - F(a) ∫ab​f(x)dx=F(b)−F(a)
Complex Combinations

You can mix normal text, inline math, and block math to create detailed explanations.

What you type:

In physics, the relationship between mass and energy is one of the most famous equations:

\[ E = mc^2 \]

Where \( E \) is energy, \( m \) is mass, and \( c \) is the speed of light (approximately \( 3 \times 10^8 \text{ m/s} \)).

How it looks:

In physics, the relationship between mass and energy is one of the most famous equations:
E=mc2 E = mc^2 E=mc2
Where E E E is energy, m m m is mass, and c c c is the speed of light (approximately 3×108 m/s 3 \times 10^8 \text{ m/s} 3×108 m/s).

Quick Tips

  • Use backslashes to escape special LaTeX characters if needed.
  • For block math, ensure there are no other characters on the same line as the delimiters for best results.
  • Complex symbols like square roots \sqrt{x} and fractions \frac{a}{b} work in both inline and block modes.
