Invenienda est in ac pars aequalis ipsi ab, quae conficiatur eodem tempore quo ipsa ab. |
| 2A
|
ab longa 4; bc 8 tempus per ab 4; ergo abc longitudo 12 conficitur in tempore 8. |
| 2B
|
Sit db 9; erit eius tempus 6, et ex d conficietur db 9 cum bce 18 tempore 12, nempe 27 in tempore 12. Sed si be conficitur (cum sit 18) tempore 6, bc conficietur tempore 2 2/3, et tota dbc in tempore 8 2/3: conficiuntur ergo citius abc quam dbc. |
| 2C
|
Sit bd 8; conficietur tempore radicis 32, idest 5 1/2, et erit be 16, et dbc conficietur tempore 8 1/4. |
