Qhov A qhov muaj nyob rau ntawm daim duab ntawm arational muaj nuj nqi ntawm ib qho input tus nqi uas ua rau ob qho tib si numerator thiab denominator ntawm lub luag haujlwm kom sib npaug rau xoom. RationalFunctionA rational function yog ib qho kev ua haujlwm uas tuaj yeem sau tau asthe piv ntawm ob lub luag haujlwm polynomial.
Ib yam li ntawd, tib neeg nug, ua li cas koj pom lub qhov hauv qhov muaj nuj nqis?
Nws muaj peev xwm muaj qhov hauv daim duab a rational muaj nuj nqi . Ua ntej muab lub rationalfunction nyob rau hauv cov nqe lus qis tshaj, ua tus lej thiab tus lej. Yog tias muaj tib yam hauv tus lej thiab tus lej, muaj a qhov . Teem qhov ntsuas no sib npaug rau zeroand daws.
Tsis tas li ntawd, dab tsi yog qhov hauv precalculus? Daim duab qhov muaj peev xwm nrhiav tau cov ntsiab lus no. Ib qho kev ua haujlwm zoo yog ib qho quotient ntawm ob lub luag haujlwm, thiab yog tias tus lej ntawm qhov quotient no muaj pes tsawg, lub rational functionis undefined ntawm qhov point. Daim duab qhov txhais tau hais tias qhia dab tsi input qhov tseem ceeb ua rau no denominator functionzero.
Ib yam li ntawd, koj tuaj yeem nug, ua li cas koj thiaj paub tias nws yog lub qhov lossis ntsug asymptote?
Ob leeg tus tus lej thiab tus denominatorbeing zero yog qhov tsim nyog tab sis tsis txaus rau a qhov ; saib piv txwv tus functionf(x)=x+1(x+1)2. Cov qhov sib txawv ntawm a qhov thiab a ntsug asymptote yog tias tus muaj nuj nqi tsis ua infinite ntawm ib qhov.
Kev siv Asymptote yog dab tsi?
Hauv lwm lo lus, qhov nkhaus thiab nws asymptote tau nyob ze, tab sis lawv yeej tsis ntsib. Asymptotes muaj ntau yam ntawm cov ntawv thov: lawv yog siv rau hauv O notation loj, lawv yog ib qho yooj yim approximations rau complex equations, thiab lawv yog cov pab tau rau forgraphing rational equations.

Dab tsi yog qhov txawv ntawm magnification thiab daws teeb meem ntawm ib daim duab nyob rau hauv lub tshuab microscope?
Magnification yog lub peev xwm ua kom cov khoom me me zoo li loj dua, xws li ua kom pom cov kab mob microscopic. Kev daws teeb meem yog qhov muaj peev xwm paub qhov txawv ntawm ob yam khoom ntawm ib leeg. Lub teeb microscopy muaj kev txwv rau ob qho tib si nws qhov kev daws teeb meem thiab nws qhov loj
Vim li cas nws thiaj li hais tias lub Orthocenter ntawm daim duab peb sab obtuse yuav tsum nyob rau sab nraud ntawm daim duab peb sab?
Nws hloov tawm tias tag nrho peb qhov siab ib txwm sib tshuam ntawm tib lub ntsiab lus - lub npe hu ua orthocenter ntawm daim duab peb sab. Lub orthocenter tsis yog ib txwm nyob hauv daim duab peb sab. Yog tias daim duab peb sab yog obtuse, nws yuav nyob sab nraud. Txhawm rau ua kom qhov no tshwm sim cov kab qhov siab yuav tsum tau txuas ntxiv kom lawv hla
Dab tsi yog qhov txawv ntawm daim duab thiab daim duab?
Ib daim duab yog ib daim duab ntawm kev ua lej, tab sis kuj siv tau (loos) txog ib daim duab ntawm cov ntaub ntawv txheeb cais.A daim duab yog ib daim duab sawv cev ntawm cov ntaub ntawv, qhov twg ib kab ntawv yog ib daim ntawv
Qhov kev hloov pauv twg yuav hloov daim duab A rau hauv daim duab B?
Ob daim duab tau hais tias yuav sib haum xeeb yog tias ib tus tuaj yeem tau txais los ntawm lwm tus los ntawm ib ntu ntawm kev txhais lus, kev xav, thiab kev sib hloov. Cov duab sib xws muaj qhov loj thiab zoo tib yam. Txhawm rau hloov daim duab A rau hauv daim duab B, koj yuav tsum xav txog nws hla y-axis thiab txhais ib chav nyob rau sab laug
Dab tsi yog qhov txawv ntawm lub xeev daim duab kos duab thiab daim duab ua haujlwm?
Lub xeev daim duab qauv yog siv los qhia qhov sib lawv liag ntawm lub xeev uas ib yam khoom mus dhau, qhov ua rau kev hloov ntawm ib lub xeev mus rau lwm qhov thiab qhov kev txiav txim uas tshwm sim los ntawm lub xeev hloov. Daim duab ua haujlwm yog ntws ntawm kev ua haujlwm yam tsis muaj qhov tshwm sim (kev tshwm sim) mechanism, lub xeev tshuab yog suav nrog lub xeev triggered
