But this amounts to saying that if we join any three of the five points by a plane, and the other two by a line, the line and plane are conjugates. This statement makes no mention of the particular point taken for centre; and we conclude as before, that... Mathematical Questions and Solutions - Page 361865Full view - About this book

The problem is therefore equivalent to that of deicribing a conic, being given the poles of certain lines. Three points and their polars are sufficient... | |
