Kodi kuchuluka kwa ntchito ndi chiyani

M'buku lino, tiwona momwe ntchitoyo ilili, momwe imapangidwira komanso kutchulidwa. Timalembanso maderawa pazinthu zodziwika kwambiri.

Lingaliro la kuchuluka

ankalamulira ndi gulu la makhalidwe x, pomwe ntchitoyo imatanthauzidwa, mwachitsanzo, ilipo y. Nthawi zina amatchedwa malo ogwira ntchito.

• x - kusinthasintha kodziyimira pawokha (kukangana);
• y - kusintha kodalira (ntchito).

Kufotokozera kwachidziwitso cha ntchito: y=f(x).

ntchito ndi mgwirizano pakati pa mitundu iwiri (ma seti). Pa nthawi yomweyo aliyense x zimagwirizana ndi mtengo umodzi wokha y.

Kutanthauzira kwa geometric kwa dera la tanthauzo la ntchito ndikuwonetsetsa kwa graph yomwe ikugwirizana nayo pa abscissa axis (0x).

Seti ya magwiridwe antchito - makhalidwe onse ykuvomerezedwa ndi ntchitoyi pa domain yake. Kuchokera pamalingaliro a geometry, uku ndikuwonetsetsa kwa graph pa y-axis (0y).

Dera la matanthauzo limatanthauzidwa kuti D (f). M'malo mwake f, motero, ntchito inayake imawonetsedwa, mwachitsanzo: D (x²), D(cos x) etc.

Ndiye chizindikiro chofanana nthawi zambiri chimayikidwa ndipo mfundo zenizeni zimalembedwa:

1. Kupyolera mu semicolon, timasonyeza malire akumanzere ndi kumanja a nthawi yomwe ikugwirizana ndi zomwe zili pa axis. 0x (momwemo mwadongosolo).
2. Ngati malirewo ali mkati mwa malo otanthauzira, ikani bulaketi lalikulu pambali pake, apo ayi, bulaketi yozungulira.
3. Ngati palibe malire akumanzere, timafotokozera m'malo mwake "-∞", chabwino - "∞" (werengani ngati "minus/plus infinity").
4. Ngati ndi kotheka, ngati mukufuna kuphatikiza magawo angapo, izi zimachitika pogwiritsa ntchito chizindikiro chapadera "∪".

Mwachitsanzo:

• [3; 10] ndi gulu la zinthu zonse kuyambira atatu mpaka khumi kuphatikiza;
• [4; 12) - kuyambira anayi kuphatikiza khumi ndi awiri;
• (-2; 7] - kuchokera kuchotsera ziwiri mpaka zisanu ndi ziwiri kuphatikiza.
• [-10; -4) ∪ (2, 8) - kuchokera kuchotsera khumi kuphatikiza anayi mpaka anayi okha komanso kuchokera pawiri mpaka eyiti mwapadera.

Zindikirani:

• Nambala zonse zokulirapo kuposa ziro zalembedwa motere: (0; ∞);
• Zonse zoipa: (-∞; 0);
• Nambala zonse zenizeni: (-∞; ∞) kapena mophweka R.
