In **witch of Agnesi** (Italian pronunciation:

The

The witch is tangent to its defining circle at one of the two defining points, and

To construct this curve, start with any two points *O* and *M*, and draw a circle with *OM* as diameter. For any other point *A* on the circle, let *N* be the point of intersection of the *OA* and the tangent line at *M*.
Let *P* be the point of intersection of a line perpendicular to *OM* through *A*, and a line parallel to *OM* through *N*. Then *P* lies on the witch of Agnesi. The witch consists of all the points *P* that can be constructed in this way from the same choice of *O* and *M*.^{[1]} It includes, as a limiting case, the point *M* itself.
