Quo circa habebitur : 



CoroII. 4. 



71. Quia igitur k fimili quoquc modo pendet a 

 p et ^, erit etiam 



kpq-'^qV{i^qq)-\pV{i-\-pp)-\k-V{i-^](k) 



Quare cum arcuum differentia fit —kpq—kef\ (i qua- 



tuor parabolae punda e, /, p, ^ ita a fe inuicem peu - 



dent, vt fit : 



g -f- V ( I -f- ? ? ) /-4- V ( '_-f-//) 



f-HV(i -+-??) — «"-Hy(i-*-ff) 

 erit 



AK.pq-Avc.ef~lqV{i+qq)-ipy{i+pp)-ifV{i+ff) 



-r-\ey{i-i-ee) 



quae expreflio, ob fundiones quant^tatum />, ^, ^,/ a fe 



inuiccm feparatas , eft notatu digna. 



Coroll. 5. 



72. Relatio inter e^f.p^q etiam ita exprimi 

 poteft , vt fit 



y( I ^]-qq)^q-{V{ i +ee)-e) {V{ 1 4-/)+/ )( V( i +/>/))+;>) 

 tum ob v(,^^' ^)^ j =3 V(i-4-^^)-^ erit: 



y(i-f^^)-^-(y(i-j-f^)-fO(y(i+/)-/)(y(i-fp;.)^/>) 



vnde datis f,/ et /), facile valor tam pro ^, quam prd 

 />, eruitur.

73- Ex formula Coroll. i. data apparet, arcum 

 pq femper maiorem fore arcu ef, fi pundlum p a
