  1. What would you do: • If you woke up and your math homework was miraculously completed? • If you could speak more than five different languages? • If your parents’ wishes differed from your personal interests and goals?

  2. Maria Gaetana Agnesi Mathematical Heron

  3. 18th Century Women • Women educated in convents • Learn to read & write • Focus on dressmaking & social graces • Some Women held jobs as university positions as assistants during Enlightenment • Priority to take care of the family and home

  9. Witch of Agnesi • Previously studied by Fermat and later by James Gregory • “Witch” is a mistranslation of a word meaning cubic curve • http://www.compasstech.com.au/ARNOLD/geogebra/witch.html View moveable applet to see how the function is created.

  10. Witch of Agnesi , L1 Q S Consider the circle with diameter PQ and center at (0, a) as shown. A tangent line L1 is constructed to the circle at point Q. A line from point P is drawn to intersect the circle at point R and extended to intersect line L1 at point S. From point S a line is drawn parallel to the y-axis, intersecting L2 at point W. Agnesi’s curve is the set of points W generated by points R on the circle. -From Sanerson & Smith p. 110 L2 W (0,2) R P
