The Instituzioni has plates of carefully numbered illustrations attached at the back of each volume. These oversized pages were to be opened outward enabling the reader to view the figures while also reading the text.  This is typical of 18th century mathematics books.


The  Equation: 

In Rectangular Coordinates

Using a diameter of a  =  2, the Witchfunction may be graphed in rectantular coordinates. 

However, the circle which is NOT a function, will be incomplete.
 

In Parametric Form
By using the parametric form, the calculator will complete the circle.
