Ib asymptote yog ib txoj kab uas daim duab ntawm ib txoj haujlwm mus txog tab sis yeej tsis kov. rational functions muaj asymptotes , raws li pom hauv no piv txwv : Hauv no piv txwv , muaj ntsug asymptote ntawm x = 3 thiab kab rov tav asymptote ntawm y = 1. Cov nkhaus mus txog cov no asymptotes tiam sis yeej tsis hla lawv.
Hais txog qhov no, qhov sib npaug asymptote yog dab tsi?
Ntsug asymptotes tuaj yeem pom los ntawm kev daws qhov kev sib npaug n(x) = 0 qhov twg n(x) yog tus denominator ntawm qhov muaj nuj nqi (nco: qhov no tsuas yog siv yog tus lej t(x) tsis yog xoom rau tib x tus nqi). Qhov no qhia peb tias y = 0 (uas yog x-axis) yog kab rov tav asymptote.
Tsis tas li ntawd, koj sau li cas asymptote? Nrhiav Kab rov tav Asymptotes ntawm Rational Functions
- Yog tias ob qho tib si polynomials yog tib qib, faib cov coefficients ntawm cov ntsiab lus siab tshaj plaws.
- Yog hais tias lub polynomial nyob rau hauv tus lej yog qis dua tus denominator, x-axis (y = 0) yog kab rov tav asymptote.
Tsuas yog li ntawd, peb hom Asymptotes yog dab tsi?
Muaj peb hom asymptotes : kab rov tav, ntsug thiab oblique asymptotes . Rau cov curves muab los ntawm daim duab ntawm kev ua haujlwm y = ƒ(x), kab rov tav asymptotes yog cov kab kab rov tav uas cov duab ntawm qhov kev ua tau zoo li x nyhav rau +∞ lossis −∞.
Yuav ua li cas koj thiaj nrhiav tau kab rov tav asymptote?
Txhawm rau nrhiav kab rov tav asymptotes:
- Yog hais tias qhov degree (qhov loj tshaj plaws exponent) ntawm tus denominator loj dua qhov degree ntawm tus lej, kab rov tav asymptote yog x-axis (y = 0).
- Yog hais tias lub degree ntawm tus zauv loj dua tus denominator, tsis muaj kab rov tav asymptote.

Hauv tib neeg, qhov muag xim yog ib qho piv txwv ntawm tus cwj pwm qub qub: ib tus neeg yuav tau txais 'xim av-qhov muag zoo' los ntawm ib tus niam txiv. Cov txiaj ntsig tau txais txiaj ntsig yog tswj hwm los ntawm cov noob thiab cov txheej txheem tag nrho ntawm cov noob hauv ib lub cev lub genome yog hu ua nws cov genotype
Ib qho piv txwv ntawm ib qho alloy yog dab tsi?
Ib qho piv txwv ntawm cov hlau yog sib xyaw ntawm cov hlau thiab hlau. Ib qho piv txwv ntawm cov hlau yog cov tin hauv qhov sib xyaw ntawm tooj liab thiab tin uas ua rau tooj liab. Lub alloy yog ib qho fusion ntawm ob lossis ntau dua hlau lossis cov hlau uas tsis yog hlau. Ib qho piv txwv ntawm cov hlau yog tooj dag, uas yog tsim los ntawm tooj liab thiab zinc
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms

Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
Qhov twg yog ib qho piv txwv ntawm ib tug dej hiav txwv continental convergent ciam teb?
Ib qho piv txwv ntawm hom dej hiav txwv-continental convergent ciam teb yog lub roob Andes ntawm sab hnub poob South America. Ntawm no Nazca phaj yog subducting hauv qab South American Phaj
