使用有道云笔记写数学公式

`math a^2 + b^3 = c

\dfrac{\tfrac{1}{2}[1-(\tfrac{1}{2})^n]}{1-\tfrac{1}{2}} = X_n

\oint_C x^3dx + 4y^3dy

\left ( \frac{(3-x) \times 2} {3-x}\right) = 2

\sum{m=1}^\infty\sum{n=1}^\infty \frac{m^2n}{3^m(m3^n+n3^m)}

\phin(\kappa) = \frac{1}{4\pi^2\kappa^2}\int0^\infty\frac{\sin(\kappa R)}{\kappa R} \frac{\partial}{\partial R}\left[R^2\frac{\partial D_n(R)}{\partial R}\right]dR `

以上公式代码如下

a^2 + b^3 = c

\dfrac{\tfrac{1}{2}[1-(\tfrac{1}{2})^n]}{1-\tfrac{1}{2}} = X_n

\oint_C x^3dx + 4y^3dy

\sum{m=1}^\infty\sum{n=1}^\infty \frac{m^2n}{3^m(m3^n+n3^m)}
