Hauv qab no yog cov daim duab ntawm rau trigonometric functions: sine, cosine, tangent, cosecant, secant, thiab cotangent. Ntawm $x$-axis yog qhov tseem ceeb ntawm lub kaum sab xis hauv radians, thiab ntawm $ y$-axis yog f (x), tus nqi ntawm kev ua haujlwm ntawm txhua lub kaum sab xis.
Xav txog qhov no, 6 lub luag haujlwm tseem ceeb yog dab tsi?
Cov ntsiab lus hauv cov teeb no (6)
- Rational (y = 1 / x) D = x tsis sib npaug rau xoom. R = y tsis sib npaug rau xoom.
- Radical (y = square cag ntawm x) D = ntau dua los yog sib npaug rau 0.
- Tus nqi tsis txaus (y = | x|) D = tag nrho cov lej tiag.
- Cubic (y = x^3) D = tag nrho cov lej tiag.
- Quadratic (y = x^2) D = tag nrho cov lej tiag.
- Linear (y = x) D = tag nrho cov lej tiag.
Tsis tas li ntawd, qhov sib txawv ntawm cov duab ua haujlwm yog dab tsi? Ntau hom ntawm daim duab nyob ntawm qhov hom kev ua haujlwm uas yog graphed. Lub yim feem ntau siv daim duab yog linear, hwj chim, quadratic, polynomial, rational, exponential, logarithmic, thiab sinusoidal. Txhua tus muaj qhov tshwj xeeb daim duab uas yog ib qho yooj yim rau visually txawv ntawm tus so.
Ua raws li qhov no, 6 leej niam txiv lub luag haujlwm yog dab tsi?
Cov theem pib muaj nuj nqi suav nrog rational muaj nuj nqi , exponential muaj nuj nqi , yooj yim polynomials, qhov tseem ceeb thiab lub hauv paus square muaj nuj nqi.
Niam txiv txoj haujlwm hauv lej yog dab tsi?
Hauv lej , a niam txiv muaj nuj nqi yog qhov yooj yim tshaj plaws muaj nuj nqi ntawm ib tsev neeg ntawm muaj nuj nqi uas khaws cia lub ntsiab lus (los yog cov duab) ntawm tag nrho tsev neeg. Piv txwv li, rau tsev neeg ntawm quadratic muaj nuj nqi muaj daim ntawv dav dav. qhov yooj yim tshaj plaws muaj nuj nqi yog.

Qhov txawv ntawm daim ntawv qhia thiab daim duab yog dab tsi?
Qhov sib txawv loj ntawm daim duab thiab daim ntawv qhia yog tias daim duab qhia chaw sawv cev rau "txoj kev" ntsug ntawm ib cheeb tsam, thaum daim duab nthuav tawm cov duab tiag tiag. Cov duab zoo tib yam uas peb paub yog coj nrog lub koob yees duab uas tuav hauv txoj hauj lwm kab rov tav
Dab tsi yog cov duab kos duab yooj yim?
Squares, rectangles, triangles, cones, cylinders, vajvoog, ovals, cov no yog cov duab yooj yim uas yuav pab koj kos duab cov khoom kom raug. Feem ntau cov duab tuaj yeem tawg ua cov duab yooj yim
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
Daim duab qhia chaw muaj txiaj ntsig dab tsi tshaj li daim duab?
Daim duab saum toj kawg nkaus muaj qhov zoo hauv qab no ntawm daim duab qhia: (1) Nws muab cov duab pom hauv av tam sim no uas tsis muaj daim ntawv qhia sib npaug. (2) Nws tau yooj yim dua. Daim duab yuav nyob rau hauv txhais tes ntawm tus neeg siv nyob rau hauv ob peb teev tom qab nws coj; daim ntawv qhia yuav siv sij hawm ntau lub hlis los npaj
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
