Haqiqatan ham bu muammo bilan juda ko'p narsa yo'q. Biz qilishimiz kerak bo'lgan narsa - bu bo'lim uchun eslatmalarda olingan formuladan foydalanish.

Chiziq segmenti,

\[\require{bbox} \bbox[2pt,border:1px solid black]{{\vec r\left( t \right) = \left( {1 - t} \right)\left\langle {0,2, - 1} \right\rangle + t\left\langle {7, - 9,2} \right\rangle \,\,\,\,\,0 \le t \le 1}}\]

\(t\)-dagi limitlarni unutmang! Busiz sizda \(\left( {0,2, - 1} \right)\) dan \(\left( {7, - 9,2} \right)\) gacha bo'lgan chiziq segmenti o'rniga ushbu ikki nuqtadan o'tadigan to'liq chiziq mavjud.
