Latex 常見錯誤整理

1. 求導

\sideset{^*}{'}\sum_{1\le i\le 100} A(i)
\qquad
\sum_{1\le i\le 100}\vphantom{\sum}^{'} A(i)
\qquad
\mathop{{\sum}'}_{1\le i\le 100} A(i)

∑∗∑′1≤i≤100A(i)∑1≤i≤100∑′A(i)∑′1≤i≤100A(i)

2. 下標

C_{1} + {C_2} \\
C_{m,n}

C1+C2Cm,n

3. 前綴

{\int_{0}^{\frac{\pi}{2}}} \\
\sum_{i=1}^{n}\\
\prod_\epsilon

∫π20∑i=1n∏ϵ

4. 佔位符

C_{1} \qquad {C_2} \\
C_{1} \quad {C_2} \\
C_{1} \ {C_2}

5. 公式對齊

$$
\begin{align}
\lim\limits_{x \rightarrow a} f(x)
&= \frac{f\left( a \right)}{ 0 !}\left( x - a \right) ^ 0 + \frac{f'\left( a \right)}{ 1 !}\left( x - a \right) ^ 1 + \frac{f''\left( a \right)}{ 2 !}\left( x - a \right) ^ 2  + \cdots + \frac{f^{(n)}\left( a \right)}{ n !}\left( x - a \right) ^ n \\
&= \sum\limits_{n=0}^{\infty} \frac{f^{(n)}\left( a \right)}{ n !}\left( x - a \right) ^ n
\end{align}
