Izinombolo Rational kanye nokusebenza kuzo

Umqondo inombolo libhekisela Abstraction ephawula intfo iphuzu ambalwa of umbono. Nokho kukhona isidingo ukusebenzisa izinto, ngakho kwakunabazalwane namagama ezinombolo angu- emphakathini bakudala abantu. Kamuva waba isisekelo wezibalo njengoba isayensi.

Ukuze umelane Tibalo.Sib, kubalulekile, okokuqala kunakho konke, cabanga ngalokho uhlobo izinombolo. Izinhlobo eziningana eziyinhloko izinombolo. Ziyakwazi:

1. Yemvelo - yibo sithola ku izinombolo lwezinto (i-akhawunti yakhe yemvelo). Iningi labo bamele Latin incwadi N.

2. ephelele (isethi yabo okhonjiswe Z incwadi). Lezi zihlanganisa zemvelo, okuphambene kubo integers engemihle futhi zero.

3. izinombolo Rational (incwadi Q). Yibo okungenzeka umelwe ingxenyenamba, le numerator zazo ilingana inenombolo, kanye zihilela - emvelo. Zonke integers futhi izinombolo zemvelo kukhona okunengqondo.

4. yangempela (yabo okhonjiswe incwadi R). Bahlanganisa izinombolo enengqondo futhi engenangqondo. Ngokuthi izinombolo engenangqondo ngu okunengqondo ethathwe imisebenzi ehlukahlukene (ukubala we logarithm impande akhiphe), ngokwabo okunengqondo.

Ngakho, noma iyiphi yalezi amasethi kuyinto isethi engezansi abalandelayo. Engokomfanekiso yalesi mqondo kuyinto umdwebo e t fomu. N. Euler imibuthano. Figure sebuningini ovals eyindilinga, ngamunye esemgwaqweni ngaphakathi kwezinye. Umuntu esinguye ngaphakathi, okusaqanda kulencane ngobukhulu (endaweni) isethi izinombolo zemvelo. Ihlanganisa ngokuphelele futhi kuhlanganisa indawo elifanekisela iqoqo integers, okuyinto yena, lingaphakathi lesizinda izinombolo enengqondo. Yangaphandle, okusaqanda enkulu, ehlanganisa bonke abanye, limelela amalungu afanayo izinombolo zangempela.

Kulesi sihloko sibheka isethi izinombolo okunengqondo, izakhiwo zawo kanye nezici. Njengoba sekushiwo, bahlanganisa zonke izinombolo ekhona (omuhle kanye engemihle futhi zero). izinombolo Rational kuyisikhalo uchungechunge elingapheli kokuba Izakhiwo ezilandelayo:

- lokhu isethi kuyalwa, okungukuthi, ukuba iyiphi pair of izinombolo kulolu chungechunge, singahlala njalo ukuthi iyiphi kuzo mkhulu;

- kokuthatha pair of lezi zinombolo, singaya noma nini ukubeka phakathi kwazo okungenani eyodwa ngaphezulu, futhi ngenxa yalokho, eziningi zalezo - izinombolo enengqondo kanjalo kuyinto uchungechunge elingapheli;

- zonke imisebenzi emine izibalo on izinombolo ezinjalo kungase kube umphumela kubo njalo inombolo ethile (enguziqu); ngaphandle kwesikhathi sesigaba ngo-0 (zero) - akunakwenzeka;

- noma iziphi izinombolo okunengqondo kungenziwa imelelwa amafrakshini wedesimali. Lezi amafraktjhini kungaba elinganiselwe noma engaphelele gqwa.

Ukuze uqhathanise izinombolo ezimbili zihlobene iqoqo okunengqondo, kumelwe kukhunjulwe:

- noma iyiphi inombolo omuhle ngaphezu kuka-zero;

- iyiphi inombolo engenhle uhlale engaphansi kuka-zero;

- uma uqhathanisa omubi izinombolo ezimbili okunengqondo mkhulu ke omunye Inani lakhe eliphelele (wemfihlo) kancane.

Kanjani ukwenza izenzo ngezinombolo enengqondo?

Ukuze Songa izinombolo ezimbili uphawu efanayo, kubalulekile ukubeka phansi izindinganiso zabo ngokuphelele futhi wabeka phambi isamba uphawu ingqikithi. Ukufaka ezinye izinombolo ngezibonakaliso ezahlukene ukuba okunenani elikhulu ongalususa kancane futhi ubeke uphawu kuzo, inani lakhe eliphelele mkhulu.

Ukuze nekususa inombolo okunengqondo kusuka kwenye inombolo esanele wengeze kuqala okuphambene yesibili. Ukuze siphindaphindeka izinombolo ezimbili udinga wande ukubaluleka amanani abo ngokuphelele. Umphumela walokhu uyoba omuhle uma izici zesibonakaliso efanayo, futhi omubi uma ehlukene.

Lesi sigaba kwenziwa ngendlela efanayo, okungukuthi, amagugu ngokuphelele ayimfihlo, futhi umphumela ibekwe phambi uphawu "+" endabeni kuqondana izibonakaliso idividendi kanye isihlukanisi, isibonakaliso "-" uma ukungafani.

Degrees izinombolo okunengqondo zivela njengoba umkhiqizo sezici ezimbalwa elilingana nomunye.
