quadratrix of Abdank-Abakanovicz

The curve has been studied by the Russian engineer Abdank-Abakanovicz (1852 - 1907), in 1889.

The curve gives the area under a circle, as function of x, so that the curve is also called the circular integral.

The curve can be constructed by the 'intergraph of Abdank - Abakanovicz', an instrument used for the construction of curves.
