Phunziro zimaonetsa kuti oyamba

Ntchito ndi kalembedwe otchedwa malo ofananira, mmene aliyense × chiwerengero akonzedwa makamaka amagwirizana nambala inayake ya kwathunthu Y.

Ntchito nthawi amaimira m'makalata Latin. Taganizirani chitsanzo aliyense f. Nambala Y womwe ndi chiwerengero cha ×, wotchedwa f mtengo kuperekedwa pa enieni mfundo x. Kodi monga: f (x). The ulamuliro wa ntchito F - ndi D (f). M'dera chomwe mfundo zonse za ntchito f (x), kumene mtsutso × mu ulamuliro wa linalake amayamikira f. Ake olembedwa monga: E (f).

Nthawi zambiri ntchito anapereka mitunduyi ndi. Choncho, pokhapokha kumatanthauza zina zopinga dera lakuti ntchito, amene anafotokozedwa ndi kachitidwe, tidzakambirana mmene ya makhalidwe variable, ndi chilinganizo amenewa chikuchitika.

Union of miyeso iwiri ndi akonzedwa, aliyense mchitidwe omwe mwina Komanso ndine mmodzi wa likulowa deta.

Akusonyeza nambala ndi malo lakuti ntchito × ena kalata anasankha, wotchedwa palokha variable kapena kukangana.

madera amene osiyanasiyana mfundo malo akuti si waika n'zosangalatsa kumva nthaŵi zambiri.

Kodi kuphunzira ntchito, zitsanzo Tingaone mothandizidwa ndi zithunzi. Chithunzi cha ntchito yake ndi kuika mfundo pa ntchito ndege, komwe mtsutso "akuthamanga" malo onse anasankha. Kwa kagawo wa ntchito ndege anali Zithunzi za ntchito yake, m'pofunika kuti kagawo ndi mfundo osachepera chimodzi chofanana ndi kufanana kulikonse mzere kuti abscissa lapansi.

Ntchito foni ku achikhalire kukula ngati mtengo wapamwamba kutsutsa zimenezi mtengo akonzedwa limafanana ndi ntchito apamwamba, natsikira kuika - ngati mtengo wapatali kwambiri ya mtsutso wa limafanana ndi mtengo wotsikitsitsa kugwira ntchito.

Pa ntchito kafukufuku pa kuwuka ndi pa mbadwa za kufunika tisonyezeni nthawi kukula ndi kuchepa kutalika pazipita.

Chithunzichi amatchedwa nthunzi ngati kuti zifukwa zilizonse dera lake lakuti kuti f (-x) = f (x), kapena unpaired - ngati zifukwa aliyense ndi kalembedwe ankalamulira ndi f (-x) = - F (x). Komanso, Zithunzi awiri ntchito adzakhala ofananira wachibale kwa Y-olamulira, ndi Zithunzi unpaired - symmetrical za mfundo (0, 0).

Kuti asalakwitse pamene ntchito ikuchitika kuphunzira, muyenera kuphunzira kupeza mbali khalidwe. Kuti tichite zimenezi, muyenera kuchita zinthu zotsatirazi:

1. Pezani malo akuti.

2. kugwira cheke pa Kumuyika kapena unpaired, komanso pafupipafupi.

3. Ndi kofunika kupeza mfundo yaikulu ya Zithunzi za reticle ndi kukhazikitsa ndi abscissa.

4. Pa nthawi imeneyi, muyenera kupeza intervals kumene ntchito ali ndi phindu zabwino, ndi kumene - negative. intervals zimenezi zimatchedwa intervals ndi zizindikiro zonse. Ndiko kuti, muyenera kudziwa kumene ndi dongosolo - pamwamba kapena pansi pa x-olamulira.

5. atsogolere kwambiri ntchito yomanga deta pa Zithunzi kuti pa malo ntchito ikukula, ndi ena amachepetsa. mipata amenewa amatchedwa intervals cm kukula ndi otsetsereka.

6. Tsopano inu muyenera kuti mupeze mfundo za ntchito pa mfundo kumene kukula m'malo kupsyolela makolo kapena mosinthanitsa.

Chotero ntchito phunziro limachititsa chiwembu ndi Zithunzi. Komanso, m'pofunika kupeza mfundo yoti kwambiri. Ndi chiyani icho?

Mfundo ndi mfundo zochepa, ngati mfundo zonse mkanganowo ndi ina osiyanasiyana adzakhala basi lochitira f (x)> f (x0).

Mfundo ndi mfundo pazipita, ngati mfundo zonse mkanganowo ndi ina osiyanasiyana adzakhala basi lochitira f (x)
