Yog hais tias lub degree ntawm tus lej yog sib npaug rau cov degree ntawm tus denominator, ces tus kab rov tav asymptote yog muab los ntawm qhov piv ntawm cov coefficients ntawm cov ntsiab lus siab tshaj plaws. Yog tias qhov degree ntawm tus lej tsawg dua qhov degree ntawm tus lej, ces tus kab rov tav asymptote yog x-axis, lossis kab y=0.
Ib yam li ntawd, koj tuaj yeem nug, ua li cas koj pom kab rov tav asymptote ntawm daim duab?
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.
Dab tsi yog cov cai rau kab rov tav asymptotes? Peb txoj cai uas kab rov tav asymptotes ua raws yog nyob ntawm qib ntawm tus lej, n, thiab qib ntawm tus lej, m.
- Yog tias n <m, kab rov tav asymptote yog y = 0.
- Yog n = m, kab rov tav asymptote yog y = a/b.
- Yog tias n > m, tsis muaj kab rov tav asymptote.
Ua raws li qhov xav tau, thaum twg daim duab tuaj yeem hla tus kab rov tav asymptote?
Cov daim duab ntawm f tuaj yeem sib tshuam nws kab rov tav asymptote . As x → ± ∞, f(x) → y = ax + b, a ≠ 0 or The daim duab ntawm f tuaj yeem sib tshuam nws kab rov tav asymptote.
Koj txhais li cas Asymptotes?
mpto?t/) ntawm ib qho nkhaus yog ib txoj kab xws li qhov kev ncua deb ntawm txoj kab nkhaus thiab txoj kab mus zero li ib los yog ob qho tib si ntawm x los yog y coordinates nyhav rau infinity.

Yuav ua li cas koj txiav txim siab yog hais tias ib tug muaj nuj nqi muaj ib tug kab rov tav tangent?
Kab rov tav kab muaj txoj kab nqes ntawm xoom. Yog li ntawd, thaum lub derivative yog xoom, cov kab tangent yog kab rov tav. Txhawm rau nrhiav cov kab kab rov tav tangent, siv qhov derivative ntawm txoj haujlwm los nrhiav qhov xoom thiab ntsaws lawv rov qab rau hauv qhov sib npaug qub
Yuav ua li cas koj nrhiav tau kab rov tav stretch?
Yog tias b> 1, daim duab ncab nrog kev hwm rau y -axis, lossis vertically. Yog hais tias b <1, daim duab shrinks nrog rau y -axis. Feem ntau, kab rov tav stretch yog muab los ntawm kab zauv y = f (cx) y = f (c x)
Vim li cas txoj kab kab rov tav muaj txoj kab nqes ntawm 0?
Mathwords: Zero Slope. Txoj kab nqes ntawm kab rov tav. Kab rov tav kab muaj nqes 0 vim tias tag nrho nws cov ntsiab lus muaj tib y-coordinate. Yog li ntawd, tus qauv siv rau txoj kab nqes ntsuas rau 0
Yuav ua li cas koj pom lub vertex ntawm kab rov tav parabola?
Yog hais tias ib tug parabola muaj ib tug kab rov tav axis, tus qauv qauv ntawm qhov sib npaug ntawm parabola yog qhov no: (y -k) 2 = 4p (x - h), qhov twg p≠ 0. Lub vertex ntawm no parabola yog ntawm (h, k). Kev tsom xam yog nyob ntawm (h + p, k). Thedirectrix yog kab x = h - p
Yuav ua li cas koj nrhiav tau kab rov tav tangent?
Kab rov tav kab muaj txoj kab nqes ntawm xoom. Yog li ntawd, thaum lub derivative yog xoom, cov kab tangent yog kab rov tav. Txhawm rau nrhiav cov kab kab rov tav tangent, siv cov txiaj ntsig ntawm kev ua haujlwm los nrhiav cov xoom thiab ntsaws lawv rov qab rau hauv qhov sib npaug qub
