Inline Math
The Pythagorean theorem states that $a^2 + b^2 = c^2$ for right triangles.
Einstein's mass-energy equivalence: $E = mc^2$.
Syntax:
Inline equation: $a^2 + b^2 = c^2$
Block Equations
$$
x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}
$$
Syntax:
$$
x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}
$$
Common Examples
Integrals:
$$
\int_{0}^{\infty} e^{-x^2} dx = \frac{\sqrt{\pi}}{2}
$$
Summation:
$$
\sum_{i=1}^{n} i = \frac{n(n+1)}{2}
$$
Matrices:
$$
\begin{pmatrix} a & b \\ c & d \end{pmatrix} \times \begin{pmatrix} e \\ f \end{pmatrix} = \begin{pmatrix} ae + bf \\ ce + df \end{pmatrix}
$$
Limits:
$$
\lim_{x \to \infty} \frac{1}{x} = 0
$$
Derivatives:
$$
\frac{d}{dx} \left( x^n \right) = nx^{n-1}
$$
Best Practices
- Use inline math
$...$for short expressions within text - Use block math
$$...$$for important equations that deserve their own line - Test complex equations to ensure they render correctly
- KaTeX supports most standard LaTeX math commands
