6224Apollonij Pergæi aggregato differentiali ab-

35[Figure 35] ſciſſarum ramorum I L, I
M ab abſciſſa rami breuiſ-
ſimi.

Pari modo in hyperbola,
& ellipſi quadratum I L ſu-
perat quadratum I M eodẽ
exceſſu, quo exemplar ap-
11Ex 9. 10. h. plicatum ad H P ſuperat
exemplar applicatum ad H
L; ſed differentia exem-
plarium applicatorum ad H
P, & H Q æqualis eſt re-
ctangulo ſub P Q exceſſu
differentiali, & recta linea
compoſita ex X m, & u l, ad quam ſumma
differentialis P H Q eandem proportionem

36[Figure 36] habet, quam latus trãſuerſum ad ſummam
in hyperbola, & ad differentiam in ellipſi
laterum tranſuerſi, & recti, vt in nota
propoſitionis 5. oſtenſum eſt; igitur quadra-
tum I L ſuperat quadratum I M iam dicto
rectangulo ſub P Q, & ſub X m, & u l,
