Draw a spiral like an ellipse
7
I am trying to draw the following diagram in latex:
I find the following command :
documentclass{article}
usepackage{tikz}
begin{document}
begin{tikzpicture}
draw [domain=0:25.1327,variable=t,smooth,samples=75]
plot ({t r}: {0.002*t*t});
end{tikzpicture}
end{document}
But it's like a circle.
Can anyone help me?

It's phase plane portrait of differential equations, x'=Ax that A=[matrix 2x2]. for more details please check the link @zyy

Your code shows a circular spiral because you punch in a circular spiral. Try e.g.
documentclass{article}
usepackage{tikz}
begin{document}
begin{tikzpicture}
draw [rotate=-45]
plot[domain=0:25.1327,variable=t,smooth,samples=75] ({t r}: {0.002*t*t} and {0.004*t*t} );
end{tikzpicture}
end{document}
And to add the axes and the arrow, you could use
documentclass{article}
usepackage{tikz}
usetikzlibrary{decorations.markings}
begin{document}
begin{tikzpicture}
draw[-stealth] (-3,0) -- (3,0) node[below]{$x$};
draw[-stealth] (0,-3) -- (0,3) node[left]{$y$};
draw [rotate=-45,postaction=decorate,decoration={markings,
mark=at position 0.93 with {arrow{latex}}}]
plot[domain=0:32,variable=t,smooth,samples=75] ({t r}: {0.002*t*t} and {0.004*t*t} );
end{tikzpicture}
end{document}
