Umsuka weCubic wenombolo

Cishe wonke umuntu uphupha ukuthuthuka, uye kokunye okubi nakakhulu. Wonke umuntu wenza ngendlela yakhe siqu. Abanye bafuna umsebenzi lapho, ngokuhamba kwesikhathi, bazothatha isikhundla sobuholi, abanye bazothola imali eyengeziwe. Sekulokhu kukholelwa ukuthi umuntu ohlakaniphile, uzobe esebenza ngokugcwele. Kodwa kukhona nalabo abathuthukisa ingqondo yabo futhi baphumelele ubuciko bokubala. Umsuka we-cube (ukubalwa kwawo) ungenye yezindlela ezivame kakhulu zokufaka "ubuchopho ngokulandelana".

Kusukela ezikhathini zasendulo kuye kwacatshangwa ukuthi ukuqeqesha ingqondo kuyindlela yokuthola ukuhlakanipha. AmaGreki asendulo, afika ezindaweni eziphakeme ezibalo, wathi "wonke umuntu uzalwa njengomuntu ohlakaniphile, kodwa akuwona wonke umuntu ongamthola ngaphakathi." Muva nje uye wathandwa kakhulu ukuthuthukisa ikhono lokuqhuba izibalo eziyinkimbinkimbi, futhi ngezinye izikhathi ezibucayi engqondweni. Impande yeCubic, engelula ukubala, uma inombolo inkulu ngokwanele - enye yezindlela. Kunezinketho eziningi ezijwayelekile zokukhipha izimpande ze-cube kusuka kwinombolo. Cabangela umbhangqwana.

Inombolo ye-Method 1

Ngezinye izikhathi ungathola ama-posters athi umuntu oyedwa wenza izibalo eziyinkimbinkimbi kakhulu engqondweni yakhe, kubandakanya ukubala impande ye-cubic. Kwaphela okwesikhashana, kwakungacacile ukuthi lokhu kwenziwa kanjani, kodwa nansi i-algorithm yokubala eyaziwa, futhi wonke umuntu angakwazi ukukhanya ngekhono lakhe.

Isizinda sempande ye-cubic senziwa "ukusika inombolo". Okokuqala udinga ukukhumbula iphethini elilula: amadijithi wokugcina kanye nomphumela we-cube, ngezinombolo ezithile, okuyi-1, 4, 5, 6 no-9 efanayo. Ake sibone isibonelo sokhonkolo. Ake sithi sidinga ukususa izimpande ze-cubic kusukela enombolweni engu-85 184. Cabangela iqembu elikhulu kunazo zonke enombolweni enikeziwe - izinkulungwane, lokhu kungu-85. Ngumuphi isibalo ku-cube esizosinika inani elilinganiselwa ku-85 kodwa ngeke lidlule? Lona inombolo 4. Manje cabangela izinombolo ezisele 184. Phawula ukuthi iphetha ngo-4. Inombolo eyodwa kuphela yamadijithali ehlinzeka ngezinga le-4 ekupheleni kwenombolo edijithali enombalwa inombolo 4. Kuvela ukuthi impendulo yombuzo Inombolo 44. Yandisa ngokwakho izikhathi ezimbili (44x44x44) bese uthola 85184.

Inombolo ye-Method 2

Izitshalo ze-cubic nazo zingasuswa ngokukhulisa inombolo kuhlelo lwe-Taylor. Noma kunjalo, le nketho yinkimbinkimbi kakhulu kuneyaphambilini. Sidinga ulwazi olucacile lwefomula lokuqothula, futhi yonke imisebenzi ngeke ibalwe engqondweni, kodwa ephepheni. Njengoba i-root cubic ukuphakanyiswa kwenombolo emandleni we-1/3, ke senza izibalo ngokukwakhiwa kwenombolo 5. Ukubeka le nombolo ibe uchungechunge lwe-Taylor, sithola impendulo, ngephutha elibi. Nokho, izibalo kwakudingeka zenziwe okuningi. Ngakho-ke, le ndlela ayiyona inzuzo kunazo zonke kusukela ekubukeni kwesikhathi sokulondoloza. Phela, uma inombolo inkulu kakhulu, khona-ke kuzothatha umzamo omkhulu wokuxazulula

Kukhona nakanjani indlela eyodwa, i-calculator. On calculators engineering kungenzeka ukukhipha impande cubic kusuka inombolo ngokuchofoza inkinobho. Njengoba sekushiwo ngenhla, kunezindlela eziningi zokukhipha izimpande ze-cube kusuka kwinombolo. Futhi sonke isikhathi kukhona abanomdlandla abazama zonke izinketho ezintsha nezinsha. Manje, uma ufuna, ungathola amatafula ngenani lezimpande ze-cubic yazo zonke izinombolo. Ungakwenza ngokwakho, kumnandi noma ngokuba "ukuhlunga ubuchopho", yakha itafula lakho. Yiqiniso, leli bhizinisi alilona usuku olulodwa, kodwa lokhu kuchitha isikhathi kungashintsha ibe yinto yokuzilibazisa eyithakazelisayo futhi engavamile. Phela, i-akhawunti, kungakhathaliseki ukuthi yikuphi, ukuqeqeshwa okuhle kakhulu kwengqondo. Into ebaluleke kunazo zonke akuyona indlela nokuthi ucabangani, kepha ngabe uyakwenza yini. Bonke abantu bahlukile, kukhona abantu abayingqayizivele abenza zonke izibalo ezinzima kakhulu ezingqondweni zabo. Lesi sipho esivela kubo ngokwemvelo. Kodwa bonke abanye bangathuthukisa lamakhono ngaphakathi kwabo. Zama, futhi mhlawumbe ulandelayo, ngubani ozovela nangenye indlela yokubala imbande ye-cubic yenombolo.
