Ikhalikuletha ye-inthanethi, isishintshi seyunithi, kanye namathuluzi emali
Ikhasi elilodwa, imisebenzi emithathu. Uthola ikhalikuletha yesayensi ephelele, isishintshi seyunithi esizamele izigaba ezingu-11, kanye nendlela esheshayo eya ohlwini lwamakhalikuletha ezezimali ohlobo lwezinqumo ezibiza imali ngempela. Akukho ukukhipha, akukho i-akhawunti, akukho ukulinda. Bhala isibalo, cindezela u-Enter, uqhubeke.
Uhlangothi lwesayensi alulona ithoyizi elinezinkinobho ezine. Lifunda izitatimende eziphelele, ngakho ungabhala (2+3)*4 noma 2^10 futhi ulishiye lihlele uhlelo lokusebenza kwezibalo. Ama-parentheses angene ajule njengoba udinga. Ngaphezu kwesibalo esijwayelekile liphatha amandla nezimpande, amaphesenti, ama-factorial, ama-reciprocal, izinto ezingashintshiyo π ne-e, kanye noqoqo olujwayelekile lwe-trig ne-log — sin, cos, tan namaphutha awo, kanye ne-log (isisekelo se-10) ne-ln (i-log yemvelo). Into eyodwa okufanele uyikhumbule: imisebenzi ye-trig icabangela imodi yakho ye-engeli. Cela i-sin(90) kumodi ye-radian futhi uzothola u-0.8939, hhayi u-1 obulindele, ngoba ama-radian angu-90 ayingeli ehluke kakhulu kunama-degree angu-90. Uma umphumela ubukeka ungalungile, yileyo nto yokuqala okufanele uyihlole.
Izici ezimbili ezincane zonga ukuxhumana okumangazayo. Izinkinobho zenkumbulo (M+, M−, MR, MC) zikuvumela ukupaka inombolo ephakathi bese uyibuyisa kamuva esikhundleni sokuyibhala kuphepha oluncane. Futhi iphaneli yomlando igcina izibalo zakho zakamuva zisondele — chofoza noma yimuphi umugqa wangaphambili ukuwufakela ngqo esibonisweni bese uqhubeka wakha kuwo. Umsebenzi wezinyathelo eziningi awuseyona umdlalo wokubambisana.
Ukushintsha amayunithi ngaphandle kokuqagela
Isishintshi sizamela izigaba eziyishumi nanye: ubude, isisindo, izinga lokushisa, indawo, ubuningi, ijubane, isikhathi, idatha, ingcindezi, amandla, kanye nengeli. Khetha isigaba, khetha amayunithi amabili, futhi impendulo iyavuseleleka njengoba ubhala — akudingeki u-Enter. Isishintshi sinyakaza ngokukhululekile phakathi kwe-metric ne-US/imperial, lapho amaphutha amaningi wansuku zonke enzeka khona.
Kungani ukugcina amayunithi ehambisana kubalulekile kangaka? Ngoba ukuxuba kubulala into ethile ngokuthula. Irisiphi lasebhulogini yase-US licela amakhomane amabili ka-flour; isikali sasekhishini sakho sifunda amagremu. Qagela, futhi isinkwa siphuma singalungile. Guqula, futhi ingaba ngamagremu angu-240 futhi uqhubeke. Noma ubhukha ihhotela phesheya futhi isibikezelo sithi ama-30°C — yisimo sasogwini noma yidinga ijazi? Yifake bese ubona cishe ama-86°F, okuxazulula impikiswano. Umqondo ofanayo wanda: ongosingasingasi nabafundi balahlekelwa amamaki (nokunye okubi) uma amaphaundi engena ngephutha esibalweni se-metric. Iphuzu lonke lesishintshi ukukhipha lowo ngozi. Izinga lokushisa lithola ukuphathwa okukhethekile, ngokungeziwe — akulona ukuphindaphinda okulula njengezinye, njengoba isikali ngasinye siqala ukubala kusuka kwelinye izero.
Ukushintsha ijubane kuvela kaningi kunoba ucabanga: isipesifiki semoto ku-mph, isivinini sokugijima ku-km/h, umoya kuma-knot. Nosayizi wedatha nawo — ukwazi ukuthi ifayela le-4 GB licishe libe ngu-4,000 MB kuyasiza uma ibha yokulanda ihamba kancane futhi uzibuza ukuthi unayo indawo.
Amakhalikuletha emali yiwo azuzayo
Izibalo ziyasiza; izibalo zezezimali yilapho izinsimbi ezincane zishintsha imiphumela emikhulu khona. Ikhasi lixhumanisa iqoqo lamathuluzi agxile, futhi ngalinye liphendula umbuzo wangempela. I-khalikuletha yenzalo enhlangene ikhombisa ukuthi inzalo etholakala phezu kwenzalo ikhula kanjani ngokuhamba kwesikhathi — kungumehluko phakathi kokuqagela ukuthi ukugcina imali kufaneleka yini nokubona ngempela umugqa. Kunekhalikuletha yesikweletu nebhondi yokwenza inhloso yenkokhelo yenyanga ngaphambi kokuba usayine noma yini, ithuluzi lokukhuphuka kwamanani elikutshela imali yanamuhla iyoba yimalini eminyakeni eyishumi, kanye nekhalikuletha ye-ROI yokulinganisela ukutshalizimali.
Kwezikhathi ezinde kunekhalikuletha ye-FIRE/yokuthatha umhlalaphansi, ithuluzi lenzuzo yesabelo, umsizi wokulinganisela isikhundla kunoma ubani ophethe ipotifoliyo, kanye nekhalikuletha yephesenti elula yezinto zansuku zonke — amathiphu, izaphulelo, izinyuko zamanani. Uma izinombolo zakho zidlula izimali, i-sixhumanisi sokushintshanisa imali sihambisana kahle nalezi, ngakho intengo noma umholo wangaphandle ufike ngezindlela ongazicabangela.
Konke kuhamba ebrowserini yakho. Akukho okulayishwayo, akukho okugcinwayo eseva, futhi akukho mgoqo wokubhalisa phakathi kwakho nempendulo. Vula ikhasi, wenze izibalo, uvale ithebhu — isibalo ngesakho futhi sihlala kudivayisi yakho. Yileyo yonke into: amathuluzi asheshayo ahlonipha isikhathi sakho nobumfihlo bakho, atholakala ngezilimi ezingu-40.
Imibuzo evame ukubuzwa
Yini ekwazi ukuyenza ikhalikuletha yesayensi?
Ihlaziya izitatimende eziphelele ezinama-parentheses, amandla nezimpande, amaphesenti, ama-factorial, izinto ezingashintshiyo pi ne-e, kanye nemisebenzi ye-trig ne-log (sin, cos, tan, log, ln). Bhala isibalo bese ucindezela u-Enter, noma usebenzise izinkinobho ezisikrinini.
Kungani umphumela wami we-trig ubukeka ungalungile?
Cishe njalo imodi yeengeli. I-sin(90) inikeza u-1 kumodi ye-degree kodwa cishe u-0.8939 kumodi ye-radian. Hlola ukuthi ikhalikuletha imiswe ku-degree noma ku-radian ngaphambi kokufunda umphumela.
Iziphi izigaba zeyunithi ezisekelwayo?
Eziyishumi nanye: ubude, isisindo, izinga lokushisa, indawo, ubuningi, ijubane, isikhathi, idatha, ingcindezi, amandla, kanye nengeli. Ngasinye sishintsha ngokukhululekile phakathi kwamayunithi e-metric ne-US/imperial.
Kungani amayunithi kufanele ahambisane esibalweni?
Ukuxuba izinhlelo kudala kuthule izimpendulo ezingalungile — amaphaundi esibalweni se-metric, amakhomane lapho kufanele kube amagremu. Ukushintsha kuqala kugcina inani ngalinye kusikali esisodwa ukuze umphumela ube ngokoqobo olungile.
Yini amakhalikuletha ezezimali angasiza ngayo?
Izinqumo zemali yangempela: ukukhula kwenzalo enhlangene, izinkokhelo zesikweletu nebhondi, umthelela wokukhuphuka kwamanani, i-ROI yokutshalizimali, ukuhlelela ukuthatha umhlalaphansi, inzuzo yesabelo, ukulinganisela isikhundla kanye namaphesenti ansuku zonke.
Ingabe konke kumahhala futhi kuyimfihlo?
Yebo. Wonke amathuluzi mahhala ngaphandle kokubhalisa, asebenza ngokuphelele ebrowserini yakho, futhi awulayishi izinombolo zakho ndawo. Asebenza ngezilimi ezingu-40.
