Inline Math The quadratic formula is $x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$, where $a \neq 0$. Euler’s identity: $e^{i\pi} + 1 = 0$. Block Math The Gaussian integral: $$\int_{-\infty}^{\infty} e^{-x^2} dx = \sqrt{\pi}$$A matrix equation: $$ A = \begin{pmatrix} a_{11} & a_{12} & a_{13} \\ a_{21} & a_{22} & a_{23} \\ a_{31} & a_{32} & a_{33} \end{pmatrix} $$Taylor series expansion: $$f(x) = \sum_{n=0}^{\infty} \frac{f^{(n)}(a)}{n!}(x - a)^n$$Programming A classic binary search in Python: ...
