# WISM100: History from Ellipse to Elliptic Curve 2016/17

This page supplements the information in Blackboard and will be updated with suggested reading, course notes, etc.

## Important: change in hand in schedule

There will be 2 papers instead of 3, with the following deadlines:
• Fri 2 June: deadline for Apollonius
• Fri 23 June: deadline for second paper with all the other stuff
Anything handed in after the deadline will suffer a grade deduction of 1 point per working day.

## First lecture

### Second part

Elliptic integrals: intro and addition forumlas NOTE: this is a jpeg image, open in an image viewer and zoom to your preferred level.

• Stillwell, Mathematics and its History, par. 12.3, 12.4, 12.5, has a easy-going introduction with nice excercises which will show you the necessary techniques. Available online in the UU library.
• If you want more about the Bernoulli's and the paracentric isochrone then have a look at Bos, The lemiscate of Bernoulli, in: Lectures in the History of Mathematics, 1993, or Blåsjö, Transcendental Curves in the Leibnizian Calculus, 2016, par. 7.3 and 8.3. It is not my intention to lay too much stress on this topic, but it may give you a clear idea of the much more geometric way of thinking in the 17th century.
• As an original source (Learn from the Masters!) Euler (site) is highly recommended. His work is indexed using Eneström index numbers, beginning with the letter E. Search for the paper E251 "De integratione aequationis differentialis mdx/√(1-x4)=ndy/√(1-y4)". There is an English translation and you can also see a scan of the original. Euler is a lucid writer so don't hesitate! You could also look around the site for other articles of Euler's under the subject "Elliptic functions".
• Fagnano's article Teorema da cui si deduce una nuova misura degli Archi Elittici... is available but much harder to read.
• Excerpts of Euler's and Fagnano's texts are contained in Dirk Struik's "Source Book in Mathematics" here. Be warned: it has a few typos.

## Second Lecture
