描述Tschirnhausen cubic.svg	English: Graph of the cubic curve ${\displaystyle y^{2}=x^{3}+3x^{2}}$ in the domain ${\displaystyle x\in [-3,2)}$. Despite the title of the image this is not the Tschirnhausen cubic, which has a different crossing angle at its double point. Plotted using 40 segments of quadratic spline for each of ${\displaystyle y<0{\text{ and }}y>0}$. Minor defects in the plotting can be observed near ${\displaystyle x=-3}$
