Kudzidza inoratidza kuti beginners

Basa aine notation kunzi enzanirana nharaunda, sezvamakaropafadzwa neimwe nhamba X kubva imwe yakatarwa inobatanidzwa imwe nhamba zvachose, y.

Basa iri kazhinji runotaurwa nemabhii Latin. Funga chinhu Somuenzaniso f. The nhamba Y, izvo unoenderana nokuwanda X, akadana f ukoshi pana nezverimwe x. Vakaita: f (x). Umambo mashandiro add - ndiye D (f). The nzvimbo chine tsika dzose mashandiro add (x), umo nharo X iri umambo inonzi umambo anokoshesa f. Her rakanyorwa se: E (f).

Kazhinji, mashandiro wakasiyiwa Masvomhu. Saka, kana rinorondedzerwa mamwe constraints nharaunda rokuti basa, izvo kunorondedzerwa yemaitiro, ichakurukurwa sezvo iine shanduka tsika, uye nzira yakadaro kuri kuitika.

Kubatanidzwa maviri seti ari yakatarwa, nechimwe chine maatomu akafanana izvo zvinogona ndezvaJehovha nhengo kupfuura rimwe date seti.

Kuratidza kuwanda pamwe nzvimbo rokuti mashandiro X dzimwe tsamba vakasarudzwa, inonzi yakazvimirira shanduka kana nharo.

munzvimbo umo siyana tsika uye nzvimbo rokuti haana kusanganiswa nemhando kazhinji kumboona.

Kana ari kudzidza basa, mienzaniso zvinogona kuonekwa tichibatsirwa Graphics. Graph mumwe Zvaiitwa ndiyo seti pfungwa pamusoro rinoronga mundege, apo nharo "anomhanya" ose akasarudzwa nzvimbo. Nokuti subset pakati rinoronga ndege yaiva girafu rimwe basa, zvakafanira kuti subset vane kanenge imwe pfungwa pachinhu chero mutsetse akaererana abscissa.

Basa kufona kuti kukura yakatarwa kana kukosha yakakwirira pamusoro nharo akadaro wakatarwa unoenderana yakakwirira basa, uye nokuburuka yakatarwa - kana chepamusorosoro kukosha nharo anoenderana yakadereresa kukosha mashandiro.

Panguva zvokutsvakurudza basa iri kuwedzera uye pamusoro anoburukira kudiwa kunan'anura nguva kukura uye huchiita kunonyanyisa urefu.

Mashandiro unonzi chiutsi kana, nokuti chero nharo rayo munzvimbo rokuti kuti F (-x) = F (x), kana unpaired - kana chipi Nharo umambo notation ndiyo e (-x) = - F (x). Uyezve, girafu basa vaviri vachava symmetric hama kuti Y-akabatana, uye ane unpaired girafu - zvakafanana, ichibata pamusoro pfungwa (0, 0).

Kuti kusakanganisa apo mabasa akaita kudzidza, unofanira kudzidza kuwana noruzhinji zvinhu. Kuti uite izvi, unofanira kuita matanho anotevera:

1. Kuwana nzvimbo izita.

2. Itirai cheki pamusoro pairing kana unpaired, uyewo maitikiro.

3. Zvakakosha kuwana pfungwa girafu pakati reticle pamwe ordinate uye abscissa.

4. Panguva ino, unofanira kuwana zvikamu apo mashandiro ane zvakanaka kukosha, uye apo - kunaka. zvikamu izvi zvinonzi zvikamu vane kugara zviratidzo. Kureva, unofanira kuona riripi purogiramu - kumusoro kana pasi X-akabatana.

5. aivabatsira zvikuru basa rokuvaka mashoko pamusoro girafu kuti dzimwe mashandiro dzezvimwe ari kukura, uye vamwe kunodzikira. Makwanza kwakadaro rinonzi spacing zvikamu kukura uye dzinza.

6. Zvino unofanira kuwana tsika mashandiro iri pfungwa apo kukura kuchatsiviwa neugari, kana vakutarisire.

Akadaro kudzidza basa runoita kuti vanofungireiko girafu. Uyezve, zvinokosha kuwana pfungwa zvokuora. Chii?

Pfungwa yacho iri shoma pfungwa, kana kuti tsika dzose nharo neumwe Range pfungwa achava chete kusaruramisira add (x)> F (x0).

Pfungwa yacho iri kufadza pfungwa, kana kuti tsika dzose nharo neumwe Range pfungwa achava chete kusaruramisira add (x)
