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

$$ \begin{align} f(x) = \frac{1}{x} \end{align} $$

$$ \begin{align} f'(x) = \lim_{h \to 0} \frac{\frac{1}{x+h} - \frac{1}{x}}{h} \end{align} $$

$$ \begin{align} x = \frac{-b \pm \sqrt {b^2 - 4ac}}{2a} \end{align} $$

$$ \begin{align} m &=& \frac{m_0}{\sqrt{1-\frac{v^2}{c^2}}} \end{align} $$

$$ \lim_{x \to p}f(x) = L $$
