The quadratic formula

x = \frac{- b \pm \sqrt{b^{2} - 4 a c}}{2 a}

Inline, in a sentence

For a right-angled triangle,

a^{2} + b^{2} = c^{2}

, and Euler's identity reads

e^{i π} + 1 = 0

.

A sum

\sum_{k = 1}^{n} k = \frac{n (n + 1)}{2}

The Gaussian integral

\int_{- \infty}^{\infty} e^{- x^{2}} d x = \sqrt{π}

The derivative as a limit

f' (x) = lim_{h \to 0} \frac{f (x + h) - f (x)}{h}

A matrix and its determinant

\det [\begin{matrix} a & b \\ c & d \end{matrix}] = a d - b c

Roots and accents

\sqrt[3]{8} = 2 | \vec{v} | = \sqrt{v_{1}^{2} + v_{2}^{2}}
