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.
