Talk:Ptolemy's table of chords/to do


 * Further inline citations, including:
 * It was the earliest trigonometric table extensive enough for many practical purposes, including those of astronomy
 * (an earlier table of chords by Hipparchus gave chords only for arcs that were multiples of 7½°).
 * Several centuries passed before more extensive trigonometric tables were created.
 * Page numbers in Glowatzki and Göttsche?
 * The parts about the three distinct methods of computing chords.


 * More on the geometric theorems: Their precise statements, how they are proved, how they are used in deriving trigonometric identities, how those identities are used in computing chords.
 * History of editions of the book including those in Arabic.
 * When did more extensive tables supersede this one? Which century?
 * How did the table influence later work?


 * And probably other things.........
