Umsebenzi wokubala: indlela yokubhala uhlelo?

Ukubheka komsebenzi kuyinkinga yeklasi yezibalo nokuhlela. Iqukethe ukulandelana ngokulandelana kokubaluleka kwe f (x) ngokulinganisa kwama- x . Imiphumela yezibalo zivame ukukhishwa njengetafula lemigqa emibili. Owokuqala uhambelana no- x , owesibili uhambisana f (x) .

Umbono

I-algorithm yokunquma amanani omsebenzi iqukethe izinyathelo eziyisithupha.

1. Ukukhethwa kokubaluleka kokuqala nokugcina kokuphikisana, inani lamaphoyinti.
2. Ukubalwa kwesinyathelo kuyigugu lapho ingxabano izoshintsha khona.
3. Ukuphikisana kuthathwa njengokulingana nenani lokuqala.
4. Ukusebenza komsebenzi.
5. Khulisa ingxabano ngenani lesinyathelo.
6. Phinda izinyathelo 4-5 kuze kube khona inombolo edingekayo yamaphuzu.

Amanani asethwe esiteji sokuqala awakhethiwe ngaso sonke isikhathi, angacaciswa ngomsebenzi. Ngokwenza njalo, isimo senzeke lapho kubalwa izinamba zamanani kanye nesiteji sokubala. Ukubethelwa komsebenzi kulokhu akudingi ukuthola inombolo yamaphoyinti, ngoba isimo sokuqedwa kwesibalo (iphuzu 6 le-algorithm) ukulingana kwempikiswano enani elinqunyiwe elilinganiselwe.

Isibonelo esiwusizo

Isibonelo sizokusiza ukuthi uqonde ukuthi ungayisebenzisa kanjani inkolelo. Vumela umsebenzi we-quadratic g ( x) = x ² + 9 unikezwe . Sakha itafula lamagugu alo ebangeni [-2; 2], ukuthatha inani lamaphuzu alingana namahlanu. Kusukela kwedatha yokuqala kulula ukulinganisa ukuthi isinyathelo sokubala kufanele silingane no-1.

Ngokuhambisana ne-algorithm, isenzo esilandelayo ukubalwa kwe- g (-2), "-2" yi-value yokuqala yalomsebenzi. Ngokukhula ngokwezibalo x ngenye (ekuhleleni lo msebenzi kuthiwa ukukhuliswa) nokuchaza umsebenzi g , umsebenzi uhlelwe.

Ukuhlola ukufaneleka kwezibalo kulula - kufanele uthole igrafu yempendulo.

Ukuqaliswa kwesofthiwe

Ukudala ithebula lomsebenzi ngesandla - umsebenzi omude. Izibalo kufanele zenziwe ngokucophelela, iphutha ekubalweni lizokwenza amanani asele abuye alungile. Isixazululo ukudlulisela umsebenzi kwikhompyutha.

Ngezansi uhlelo lwamathebhu lomsebenzi ku okuthiwa "i-pseudocode". Ukuyikhipha, kufanele ucacise umsebenzi, inani lokuqala nelokugcina lamaphuzu, inani lamaphoyinti. Esikhathini, f (x) = 18 * x + 5 ibalwa. Umphumela waloluhlelo yizindinganiso ezithathwe ngokulandelana ze x , f (x) .

- Ukuphikisana: = N.Value.

- Isinyathelo sokubala: = (N. value - K. value) / Col. Amaphuzu.

- FOR (Counter: = 0 kuya Inani lamaphuzu).

Qala:

- Umsebenzi: = 18 * Ukuphikisana + 5.

- Ukuphikisana: = H. value + Counter * Isinyathelo.

- Ukukhipha kwesikrini (Ukuphikisana, Umsebenzi).

Ukuphela.

Ikhodi ivumelanisa nanoma yiluphi ulimi lohlelo. Lokhu kungukuthi, ukubethelwa komsebenzi kungasetshenziswa ku-Pascal, C +, C # futhi ngisho nolimi lwe-program ye-VBA yohlelo lokusebenza, oluhlanganisiwe kwiphakethe le-MS Office.
