Biquadratic, biquadratic maikwezhoni njira

Aliyense kusukulu ndi mfundo kudziwika monga aone kuti pali lapansi. Aone kuti pali - azimai munali zosintha umodzi kapena kuposerapo. Kudziwa gawo la aone kuti pali zimenezi n'zofanana kwa ena, n'zotheka kupeza mbali ya aone kuti pali la, posamutsa zina mwa zigawo zake kwa chizindikiro ofanana malamulo zodziwika bwino. Aone kuti pali akhoza wosalira kumaliza mfundo zofunika mu mawonekedwe × = N, kumene N - ndi inteja iliyonse.

Ku sukulu ya pulayimale, ana onse ankachitira ndi kafukufuku wa maikwezhoni liniya wa kusinthasintha kwambiri. Kenako mu pulogalamu kuoneka zovuta kwambiri maikwezhoni liniya - lalikulu, kenako aone kuti pali kiyubiki. Aliyense mtundu wotsatira wa maikwezhoni ndi njira yatsopano ya kuthetsa, izo zimakhala zovuta kwambiri kuphunzira komanso kubwerezabwereza.

Koma funso n'lakuti kuthetseratu mtundu wa aone kuti pali ndi biquadratic aone kuti pali. Zimenezi, ngakhale zovuta akuoneka ndi kuthetsedwa ndithu chabe, chinthu chachikulu - athe kutsogolera maikwezhoni ngati mu mawonekedwe woyenera. kusankha kwawo kuphunzira maphunziro imodzi kapena ziwiri pamodzi ndi ntchito zothandiza, ngati ophunzira mfundo zofunika kuthetsa maikwezhoni quadratic.

Kodi mukufuna kudziwa munthu akakumana ndi mtundu uwu wa maikwezhoni? Kuyamba ndi chakuti iwo amaphatikizapo kokha ngakhale mphamvu za variable "X": wachinayi ndipo motero, wachiwiri. Kuti biquadratic aone kuti pali anali anathana, m'pofunika kulowa mawonekedwe a aone kuti pali quadratic. Kodi kuchita izo? Osavuta! ochepa okha m'malo "X" mu bokosi pa "Y". Ndiye mantha kwa ophunzira ambiri "X" mu wachinayi digiri kuwasandutsa "Y" pabwalopo, ndi aone kuti pali amakhala lalikulu wamba.

Kenako, iwo anaganiza monga wamba quadratic aone kuti pali ali decomposed mu zinthu, ndiyeno mtengo ndi zachinsinsi "Y". Kuti athetse biquadratic aone kuti pali mapeto, muyenera kupeza muzu lalikulu chiwerengero cha "Y" - uyu adzakhala osadziwika kuchuluka "X", pambuyo kupeza kuti makhalidwe adzakhala kudzamuthokoza okha pa bwinobwino kuwerengetsera.

Kodi tiyenera kukumbukira kuthetsa maikwezhoni wa mtundu uwu? Choyamba ndi chofunikira: Y sangakhale zoipa! The chikhalidwe kwambiri kuti Y - chiwerengero apakati X, nadzatonza zoterezi njira mwina. Choncho, ngati zochita yoyamba ya aone kuti pali biquadratic wa munthu wa "Y" mfundo analandira ndi zabwino, ndipo chachiwiri - ayi, muyenera kokha njira zabwino, kapena biquadratic aone kuti pali adzathetsedwa molondola. Bwino chabe kuti atchule lamulo kuti variable "Y" ndi wamkulu kuposa kapena wolingana ndi ziro.

The chachiwiri zofunika mwatsatanetsatane: chiwerengero cha "X", kukhala muzu lalikulu chiwerengero cha "Y" ikhoza kukhala zabwino kapena zoipa. Mwachitsanzo, ngati "Y" ndi wofanana ndi zinayi, anthu aone kuti pali biquadratic adzakhala ndi njira ziwiri: awiri ndi opanda awiri. Izi zimachitika chifukwa chakuti chiwerengero zoipa anamuukitsa kwa mphamvu, wofanana chiwerengero cha gawo lomwelo, koma chizindikiro chachikulu anamangidwa mu mlingo chomwecho. Choncho nthawi zonse zofunika kukumbukira mfundo yofunika iyi, mwinamwake inu basi kutaya chimodzi kapena zingapo mwa mayankho a aone kuti pali lapansi. Ndi bwino kulemba kuti "X" ndi wofanana kuphatikiza kapena opanda muzu lalikulu la "Y".

Nthawi zambiri, chitsimikizo choti maikwezhoni biquadratic - ndi losavuta mokwanira ndi sikutanthauza nthawi yambiri. Pa kuphunzira phunziro ili mu maphunziro kusukulu sadziwa maola awiri maphunziro - osati kuwerengera, ndithudi, kubwereza ndi kulamulira ntchito. muyezo mawonekedwe biquadratic maikwezhoni zingathe kuthetsedwa mosavuta kwambiri ngati mutsatira malamulo pamwamba. njira zawo sadzakhala inu palibe vuto, chifukwa utoto mwatsatanetsatane mu mabuku a masamu. Zabwino zonse ndi maphunziro anu ndi bwino kuthetsa iliyonse, osati masamu, mavuto!
