I am trying to reproduce the picture below using TikZ.
A similar question was already asked here, but I wasn't able to apply the answers to my problem since I need the exact same picture not only the shapes. I tried to modify the given answers but that didn't lead to anything useful because I don't really understand pgfplots
and I'm relatively new to TikZ ...
That is what I have done so far.
\begin{tikzpicture}
\foreach \x in {0,4.5,9,13.5}{
\draw [->] (-1.2-\x,0)--(2.5-\x,0);
\draw [->] (0-\x,-1.2)--(0-\x,1.7);
\draw[shorten <=-1cm, shorten >=-3mm] (0-\x,1)--(2-\x,0) node [midway, above] {$A$};
}
\draw[blue] (-10,0)--(-9,1)--(-8,0)--(-9,-1)--cycle;
\draw [blue](-4.5,0) circle (0.88cm);
\foreach \x in {0.66}{
\draw[blue] (-\x,-\x)--(-\x,\x)--(\x,\x)--(\x,-\x)--cycle;
}
\draw[blue,scale=1,domain=0:90,samples=100,smooth,variable=\t]
plot({-1*cos(\t)^(3)-13.5},{1*sin(\t)^(3)});
\draw[blue,scale=1,domain=0:90,samples=100,smooth,variable=\t]
plot({-1*cos(\t)^(3)-13.5},{-1*sin(\t)^(3)});
\draw[blue,scale=1,domain=0:90,samples=100,smooth,variable=\t]
plot({1*cos(\t)^(3)-13.5},{-1*sin(\t)^(3)});
\draw[blue,scale=1,domain=0:90,samples=100,smooth,variable=\t]
plot({1*cos(\t)^(3)-13.5},{1*sin(\t)^(3)});
\end{tikzpicture}
The picture below shows the result. The code is horrific but it is the best I can come up with for now ...
edit
in your question, paste your code, mark it, then click on the{}
symbol. your code will be displayed on a grey background.
