## Equation Example 
(not important, just for MD testing purpose)

% Aligned environment
$$
\begin{equation}
\begin{aligned}
    f(u) & =\sum_{j=1}^{n} x_jf(u_j)\\
         & =\sum_{j=1}^{n} x_j \sum_{i=1}^{m} a_{ij}v_i\\
         & = \sum_{j=1}^{n} \sum_{i=1}^{m} a_{ij}x_jv_i
\end{aligned}
\end{equation}
$$

% Remove numbering in multiline equations 2 (doesn't work in HackMD)
$$  
\begin{flalign*}
f(u) & =\sum_{j=1}^{n} x_jf(u_j)&\\ \nonumber
     & =\sum_{j=1}^{n} x_j \sum_{i=1}^{m}  a_{ij}v_i&\\ \nonumber
     & =\sum_{j=1}^{n} \sum_{i=1}^{m} a_{ij}x_jv_i
\end{flalign*}
$$  
\begin{equation}  
\begin{aligned}
\end{aligned}
\end{equation}  


電容與電感中所儲存 **能量的變化** 是 **功率** \(p\) 
$$p_{abs} = \frac{d}{dt} \cdot (v_{C}^2) \cdot C$$
$$p_{abs} = \frac{d}{dt} \cdot (i_{L}^2) \cdot L$$
