Umsebenzi Ukubala: ukubhala njani inkqubo?

umsebenzi Ukubala - ngxaki classical yezibalo kunye nokufakwa kweenkqubo. It iqulathe ekufumaneni amaxabiso olulandelelanayo f (x) kunye neenqobo ezahlukahlukeneyo x. iziphumo Calculation rhoqo ofakwe njenge itafile imikrozo emibini. Le liyangqinelana ukuba x wokuqala, wesibini - f (x).

theory

Algorithm yokuqingqa amaxabiso umsebenzi yenziwa ngamanyathelo amathandathu.

1. Ukukhetha amaxabiso sokuqala nesokugqibela Kwempikiswano, inani lamanqaku.
2. Indlela yokubala inyathelo - yemali ingxabano iya kutshintsha.
3. Le ngxoxo kuthathwa elingana nexabiso lokuqala.
4. umsebenzi ukubala.
5. Ukwandisa ixabiso ingxabano kwinqwanqwa.
6. Umkhuba 4-5 logama nje kungekho elifunekayo inani eliqikelelwayo lamanqaku.

Iinqobo ebekwe kwi inyathelo lokuqala, akusoloko ekhethiweyo, ukuba banikwe umsebenzi. Ukuziqhelisa, kukho imeko xa anikwe kumqolo lwamaxabiso kunye ikhompyutha inyathelo. umsebenzi ukubala kulo mzekelo ayifuni ukufumana inani amanqaku, kuba ukubala imeko ukupheliswa (inyathelo 6 algorithm) iya kulingana ngexabiso ekujoliswe kuzo ingxabano.

Umzekelo practical

Ukwazi ukuba kusetyenziswa njani le ngcamango ukunceda umzekelo. Makhe umsebenzi quadratic lwe G (x) = x ² + 9. Yenza itheyibhile imilinganiselo yayo kuluhlu [-2; 2] ngokuthatha inani leendawo kuphuma isihlanu. Ukususela data lokuqala kulula ukuqikelela ukuba inyathelo ubalo kufuneka alingane 1.

Ngokutsho algorithm, inyathelo elilandelayo ukubalwa g (-2), «-2» - ixabiso lokuqala lomsebenzi. Ngokulandelana ukwandisa x ngamnye (kulo msebenzi lokuprograma kuthiwa incrementing) nokumisela umsebenzi g olwenziwa umsebenzi ukubala.

Tshekisha ukuchaneka kwazo ukubala kulula - kufuneka ukufumana igrafu a parabola.

ukuqaliswa software

itheyibhile ukuyila iimpawu ngesandla - yayisengumsebenzi elide. Ukubala kufuneka wenziwe ngocoselelo, impazamo ekubaleni kwezinye ukwazisa ukuba ayilunganga. Isisombululo - Kwathi ingxaki kwi computer.

Apha ngezantsi kunikwe inkqubo ukubala olona babizwa ngokuba "pseudo." Ukuze enze oko, kufuneka ukhankanye umsebenzi, ukuqala nokuphela kwiimpikiswano, inani lamanqaku. Umzekelo ikuhluza f (x) = 18 * x + 5. Isiphumo senkqubo - ngokulandelelana ethatyathwe imilinganiselo x, f (x).

- Ingxoxo: = N.Znachenie.

- Shag_vychisleny: = (ixabiso N. - K ixabiso) / Inombolo. amanqaku.

- FOR (Counter: = 0 ukuya Bala amanqaku.).

qala:

- Umsebenzi: = 18 + 5 * ingxabano.

- Ingxoxo: NA = ixabiso + Inyathelo Counter.

- Bonisa (function ingxoxo).

End.

Code lulungiselelwe ukuba naluphi ulwimi lokuprograma. Yiloo nto ke ukubala kwemisebenzi lingaphunyezwa njani i "Pascal", C +, C #, kwaye nkqu VBA software ofisi edityanisiweyo kulo mqulu MS Office.
