An isoptic of a given curve C is a set of points from which this curve is seen under the fixed angle [alpha], where [alpha] [member of] (0, [pi]).
In [8] we defined secantoptics, a generalization of isoptic curves of ovals.
The isoptic [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII.] and the secantoptic [C.[alpha],[beta],[gamma]] of a given oval C coincide if [beat] [member of] [0, [pi]), [beta]), [gamma] [member of] [0, [pi] - [beta]) and [alpha] [member of] ([beta] + [gamma], [pi]).
The equation of the isoptic [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII.], where [beta] [member of] [0, [pi]), [gamma] [member of] [0, [pi] - [beta]) and [alpha] [member of] ([beta] + [gamma], [pi]) can be written as
for a given oval C the isoptic [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII.] is the same curve as the secantoptic [C.sub.[alpha],[beta],[gamma]] under the assumption that [beta] [member of] [0, [pi]), [gamma], [member of] [0, [pi] - [beta]) and [alpha] [member of] ([beta] + [gamma], [pi]).
