Title: Plotting an Equation of the Form f(x, y) = 0 in the Plane using pgfplots
Tags: tikz-pgf;pgfplots
Question: I want to plot the blue curve defined by the equation (color blue) in the Cartesian plane. There is a problem with my parametrization since it is not defined at x = 0. Hence, the generated plot is discontinuous and certainly does not look like the curve from the image.
\addplot[penColor, very thick, samples = 100] ({(-2*x-1)/x^3}, {(-2*x-1)/x^2});
