1.一般公式
y=x^2
\dfrac{\tfrac{1}{2}[1-(\tfrac{1}{2})^n]}{1-\tfrac{1}{2}}=s_n
2=\left(\frac{(3-x) \times 2}{3-x}\right)
\sum_{m=1}^\infty\sum_{n=1}^\infty\frac{m^2\,n}{3^m\left(m\,3^n+n\,3^m\right)}
\phi_n(\kappa)=
\frac{1}{4\,\pi^2\,\kappa^2}
\int_0^\infty
\frac{sin(\kappa\,R)}{\kappa\,R}
\frac{\partial}{\partial\,R}
