The imaginary domains of conics and their interpretation in the complex plane (1912)
Wilson, Charles Richard · leaf 84
ut the line drawn through b^ c^, and B^ passes thru e-^ f-j_. How-ever since these two tangents coincide, this point of intersectionis the point of tangency, which is T^. 2. In a similar way, by choosing the tangents a2, b2, c2, d2,and e2 as in the figure and the Brianchon Point B2 at infinity… … Fi^. 7. 38 as in the figure and B3 at infinity on the line through a3 t>3 andd3 e3* we find that tne tangents e3 and f3 coincide and the pointof tangency is Tg. Prom the construction, we can easily see that the linesdrawn through opposite points of tangency are conjugate diametersand intersect…
