Inversions in an ellipse - José L. Ramírez In this paper we study the inversion in an ellipse which generalizes the classical inversion with respect to a circle and some properties. We also study the inversive images of lines, ellipses and other curves. Finally, we generalize the Pappus chain theorem to ellipses. ✪ ✪ ✪ ✪ ✪ Link tải tài liệu: LINK TẢI TÀI LIỆU Theo LTTK Education
