Probemus autem quod talis curva sit parabola
sit LX aequ X. sit 1X 1T aequ y.
fist: et sit ac  2bx aequy y
seu rbdx aequ 2y dy seu dy: dx v: b. y.
Sive dy Ergo dy aequ bdx y seu erit
des ago V dx y. seu dius aequ bx b : bx
seu aus aequ. b dx. X.
des aqu. Ox dx 1b.
et sit XX aequ 2by. fiet 2X dx aegurbay
seu dy aequ. Xdx: b. seu dx: dy: : b: x
Est autem dx: dy 1:: cox 2XC: 2X2
Ergo erit 2X Cd ad 2X 2T, ut b ad X
ut constans ad 82X. quae constans ut
inveniatur ducenda est langens aliqua ut
