TitlePaper, 'Note of a theory of orthoptic and isoptic loci' by Charles [M] Taylor
CreatorTaylor; Charles M (fl 1884)
Date1884
DescriptionTaylor writes: 'The orthoptic locus of a curve and its isoptic loci are the loci of the points of concourse of pairs of tangents drawn to it at right angles, and at angles equal to given angles, respectively. As a step towards a general theory of such loci, of which special cases only have been treated hitherto, it is shown below that the order of the orthoptic locus of a curve of class n is n(n—1), and the order of its isoptic loci 2n(n—1).'
