使用以下代码,我得到
\documentclass[11pt]{scrartcl}
\usepackage{tikz,tkz-tab,amsmath}
\usetikzlibrary{arrows}
\begin{document}
\begin{tikzpicture}
\tikzset{arrow style/.style = {blue,->,> = latex',
shorten > = 6pt,
shorten < = 6pt}}
\tkzTabInit[espcl=5]{$x$ /1, $f(x)$ /1.5, $g(x)$ /2}{$0$ ,$1$ , $+\infty$}%
\tkzTabLine{d,-,z,+,}
\tkzTabVar%
{ D+/ / $0$ ,%
-/ -2/ ,+/ $+\infty$ / }%
\end{tikzpicture}
\end{document}
我明白了
我想删除上面表格的第一行。也就是说,我想得到
答案1
像这样:
\documentclass[11pt]{scrartcl}
\usepackage{tikz,tkz-tab,amsmath}
\usetikzlibrary{arrows}
\begin{document}
\begin{tikzpicture}
\tikzset{arrow style/.style = {blue,->,> = latex',
shorten > = 6pt,
shorten < = 6pt}}
\tkzTabInit[espcl=5]{$x$ /1, $g(x)$ /1}
{$0$ ,$1$ , $+\infty$}%
\tkzTabVar%
{ D+/ / $0$ ,%
-/ -2/ ,+/ $+\infty$ / }%
\end{tikzpicture}
\end{document}
