求根公式:

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

矩阵:

$$ \left[\begin{array}{cccc} 1 & x_1 & y_1 & z_1 \\ 1 & x_2 & y_2 & z_2 \\ 1 & x_3 & y_3 & z_3 \\ 1 & x_4 & y_4 & z_4 \end{array}\right] \left[\begin{array}{c} a_1 \\ a_2 \\ a_3 \\ a_4 \end{array}\right] = \left[\begin{array}{c} T_1 \\ T_2 \\ T_3 \\ T_4 \end{array}\right] $$

来个几个看不懂的,嘿嘿 高斯公式:

$$ \iiint_\Omega( \frac{\partial P}{\partial x} +\frac{\partial Q}{\partial y} +\frac{\partial R}{\partial z})dv =\oint_S Pdydz+Qdzdx+Rdxdy $$

薛定谔方程:

$$ i\hbar\frac{\partial \psi}{\partial t} = \frac{-\hbar^2}{2m} \left( \frac{\partial^2}{\partial x^2} + \frac{\partial^2}{\partial y^2} + \frac{\partial^2}{\partial z^2} \right) \psi + V \psi $$
