# Math (KaTex)

$$ f(x) = \int_{-\infty}^\infin \hat f(\xi) e^{2 \pi i \xi x}\ d\xi $$

When $ a \ne 0 $, there are two solutions to $ (ax^2 + bx + c = 0) $ and they are $$ x = {-b \pm \sqrt{b^2-4ac} \over 2a} $$

The Cauchy-Schwarz Inequality

$$\left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)$$
