简单公式

$$ e^x=\lim_{n\to\infty} \left( 1+\frac{x}{n} \right)^n \qquad (1) $$ $$ x_1 = \frac{-b+\sqrt{b^2-4ac}} {2a} \qquad (2) $$ $$ x_1 = \frac{-b-\sqrt{b^2-4ac}} {2a} \qquad (3) $$

使用LaTeX语法对齐

\begin{align} \sqrt{37} & = \sqrt{\frac{73^2-1}{12^2}} \\ & = \sqrt{\frac{73^2}{12^2}\cdot\frac{73^2-1}{73^2}} \\ & = \sqrt{\frac{73^2}{12^2}}\sqrt{\frac{73^2-1}{73^2}} \\ & = \frac{73}{12}\sqrt{1 - \frac{1}{73^2}} \\ & \approx \frac{73}{12}\left(1 - \frac{1}{2\cdot73^2}\right) \end{align}
