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

f (a) = \frac{1}{2 π i} \oint \frac{f (z)}{z - a} d z

σ = \sqrt{\frac{1}{N} \sum_{i = 1}^{N} (x_{i} - μ)^{2}}

\int \frac{1}{a x + b} d x = \frac{1}{a} \ln | a x + b | + C

\vec{\nabla} \times \vec{F} = (\frac{\partial F_{z}}{\partial y} - \frac{\partial F_{y}}{\partial z}) i + (\frac{\partial F_{x}}{\partial z} - \frac{\partial F_{z}}{\partial x}) j + (\frac{\partial F_{y}}{\partial x} - \frac{\partial F_{x}}{\partial y}) k
