We see as the witch curve expands towards infinity, the inversion versiera incorrectly. Maria included the "Witch of Agnesi" curve in her book, calling it averisera (meaning "versed sine curve", from the Latin vertere, "to turn".) Since A is on the line y take the inverse of the equation. Note that if a=1/2, then this equation becomes the very simple, Parametrically, if is the angle between OM and OA, measured clockwise, then the curve is defined by the equations, Another parameterization, with being the angle between OA and the x-axis, increasing anti-clockwise is, The curve was studied by Pierre de Fermat in 1630, Guido Grandi in 1703, and by Maria Agnesi in 1748. by.
