Placing a Tikzpicture and Matrix together












2














I need help a little on the matrix again and putting together the matrix and tikzpicture I created.



documentclass{article}
usepackage{tikz,amsmath}
usetikzlibrary{decorations.pathreplacing} %%% For curly braces
usetikzlibrary{shapes.arrows,matrix,positioning}


begin{document}

The Tikzpicture

begin{center}
begin{tikzpicture}
draw[<->,black,thick] (0,0)--(9,0);
draw (3,2pt)--(3,-2pt) node[below] {textcolor{red}{$-3$}};
draw (6,2pt)--(6,-2pt) node[below] {textcolor{red}{$3$}};
draw[decoration={brace,raise=5pt},decorate]
(0,0) -- node[above=6pt,align=center] {$(-infty,3)$} (2.95,0);
draw[decoration={brace,raise=5pt},decorate]
(3.05,0) -- node[above=6pt,align=center] {$(-3,3)$} (5.95,0);
draw[decoration={brace,raise=5pt},decorate]
(6.05,0) -- node[above=6pt,align=center] {$(3,infty)$} (9,0);
end{tikzpicture}
end{center}

The Matrix

begin{center}
begin{tikzpicture}[wide/.style={text width=#1,fill=green!40!gray}]
matrix[matrix of nodes,nodes={align=center,inner sep=3pt,anchor=center,
ultra thin,draw},draw,inner
sep=0pt,ampersand replacement=&] (mat1)
at (0,0){
f^{prime}(-4)>0 & f^{prime}(0)<0 & f^{prime}(4)>0 \
|[text width=33mm,wide=33mm]| {text{Test Value}} &
|[text width=33mm,minimum height=.5cm]| {$x=-4 $} &
|[text width=33mm,minimum height=.5cm]| {$x=0$} &
|[text width=33mm,minimum height=.5cm]| {$x=4$} & \
|[text width=33mm,wide=33mm]| text{Sign of $f^{prime}(x)$} &
|[text width=33mm,minimum height=.5cm]| {$f^{prime}(-4)>0$} &
|[text width=33mm,minimum height=.5cm]| {$f^{prime}(0)<0$} &
|[text width=33mm,minimum height=.5cm]| {$f^{prime}(4)>0$} & \
|[wide=33mm]| {strut Result\} &
|[text width=33mm]| {strut $f$ is increasing \ on $(-infty,-3)$} &
|[text width=33mm]| {strut $f$ is decreasing \ on $(-3,3)$} &
|[text width=33mm]| {strut $f$ is decreasing \ on $(3,infty)$} & \
};
end{tikzpicture}
end{center}

end{document}

          sorry, but to me it is not clear, if you like to have red arrows and text below matrix on image too. let me know, that i will add them.

          • this is fantastic! Yes if you could add the text below, that would be great!

          • @MathScholar, done. also added missed end part of the mwe (happen at copy-past procedure ...)

          • @Zarko, I feel my minimal example had nothing to do with the final solution. Thank you very much for this. Studying the manual must have taken you to this level of programming. I would not have been able to write on my own at this time!

          sorry, but to me it is not clear, if you like to have red arrows and text below matrix on image too. let me know, that i will add them.

          • @Zarko, I feel my minimal example had nothing to do with the final solution. Thank you very much for this. Studying the manual must have taken you to this level of programming. I would not have been able to write on my own at this time!
