The prime symbol is available on your computer keyboard. However, you should also have an idea about the various latex packages and commands.
\documentclass{article}
\begin{document}
a' f' c'
\end{document}
\[a’ \quad f’(x) \quad c’\]
Notice the output above, you cannot use the direct prime symbol as a latex command in text mode. Because it will return the single left quotation mark. So, the prime symbol has to be used in math mode.
\documentclass{article}
\begin{document}
a$'$ b$'$ c$'$
$ a' b' c' $
\end{document}
\( a′ \quad b’ \quad c′ \)
\(a′ \quad f’(x) \quad c′ \)
\prime command must be used in math mode. However, it will take the place of inline text. For example
\[ f\prime(x) \]
\[ f\prime(x) \]
The above output is not very accurate. Because the prime symbol is always located along the top corner.
So, you can pass in superscript without using a direct prime command. Now you notice the output below.
\documentclass{article}
\begin{document}
\[ a^{\prime} \]
\[ b^{\prime} \]
\[ c^{\prime} \]
\end{document}
Output :
a′ b′ c′
Double and triple prime symbols in LaTeX
Mathematically, the prime symbol is used in calculus to represent the derivative of a function.
\documentclass{article}
\begin{document}
\[ f'(x) \]
\[ f''(x) \]
\[ f'''(x) \]
\end{document}
\[ f'(x) \]
\[ f”(x) \]
\[ f”'(x) \]
