Problema. 



ropofita hac formula differentiali: 



(i -h z z) / (i -4- 6 z z -f- !E^)' 

 eius integraU:, per logarithmos et arcus circulares expreffumj 



muenire. 



Solutio. 



J. 1. Ponatur breuitatis gratia y (i -t- <Jz z-+- s'*)-!;, 

 Vt formula propofita fit d V = ^? i — zzf . ^^ nunc loco % binae 



variabiles petqf in calculum introducantur, ponendo p-^-^ 



et q ■=. i=^, eritque p^^-^q^—^ ideoque p^ dp-^ q^ d q — O,
