$These are two truth tables for the following:


$\neg (p \vee q)$ is logically equivalent to $(\neg p) \wedge (\neg q)$

\begin{tabular} {|c|c||c|c||c|c|c|}\hline
$p$ & $q$ & $p \vee q$ & $\neg (p \vee q)$ & $\neg p$ & $\neg q$ & $(\neg p) \wedge (\neg q)$\\ \hline
T & T & T & F & F & F & F\\
T & F & T & F & F & T & F\\
F & T & T & F & T & F & F \\
F & F & F & T & T & T & T\\ \hline
\end{tabular}  \vskip .5cm

$\neg (p \implies q)$ is logically equivalent to $p \wedge(\neg q)$

\begin{tabular} {|c|c||c|c||c|c|c|}
\hline
$p$ & $q$ & $(p \implies q)$ & $\neg (p \implies q)$ & $p$ & $\neg q$ & $p \wedge (\neg q)$\\ \hline
T & T & T & F & T & F & F\\ 
T & F & F & T & T & T & T\\ 
F & T & T & F & F & F & F\\ 
F & F & T & F & F & T & F\\ \hline
\end{tabular} \\ \vskip .5cm

$This is some practice using LaTex:
\[
\frac{x^4+5x^3-y}{\cos y-x^2}
\]
\[
\sqrt[\frac{x62}{3}]{\frac{\cos 4}{4.2}}
\]

我知道这是一份练习文件，但为了以防万一，在实际文件中必须避免连续显示两个表达式。
