TitlePaper, 'On the rectification of the hyperbola by means of two ellipses; proving that method to be circuitous, and such as requires much more calculation than is requisite by an appropriate theorem: in which process a new theorem for the rectification of that curve is discovered' by Rev John Hellins
Date[1811]
DescriptionSubject: Geometry

Published in Philosophical Transactions as 'On the rectification of the hyperbola by means of two ellipses; proving that method to be circuitous, and such as requires much more calculation than is requisite by an appropriate theorem: in which process a new theorem for the rectification of that curve is discovered. To which are added some further observations on the rectification of the hyperbola: among which the great advantage of descending series over ascending series, in many cases, is clearly shown; and several methods are given for computing the constant quantity by which those series differ from each other'.

Communicated by Nevil Maskelyne. Read 10 January 1811.

Abstract published in Abstracts of the Papers Printed in the Philosophical Transactions of the Royal Society of London [later Proceedings of the Royal Society of London], Volume 1, 1832.
