Rau nrhiav cov nqes hav ntawm ob qhov ntsiab lus muab, koj tuaj yeem siv qhov point- nqes hav cov qauv ntawm (y2 - y1) / (x2 - x1). Nrog cov ntsiab lus ntsaws rau hauv, cov mis zoo li (3 - 2) / (4 - 1). Yooj yim rau cov mis kom tau txais nqes hav ntawm?.
Hauv txoj kev no, cov mis twg thiaj nrhiav tau txoj kab nqes?
Muaj peb theem hauv kev suav qhov nqes hav ntawm txoj kab ncaj thaum koj tsis muab nws qhov sib npaug
- Kauj Ruam Ib: Txheeb xyuas ob lub ntsiab lus ntawm kab.
- Kauj Ruam Ob: Xaiv ib qho los ua (x1, y1) thiab lwm qhov yog (x2, y2).
- Kauj Ruam Peb: Siv txoj kab nqes los xam qhov nqes hav.
Kuj Paub, koj pom li cas txoj kab nqes ntawm txoj kev tawg? Cov kab nqes hav sib npaug qhov sib txawv ntawm cov ntsiab lus 'y-coordinates faib los ntawm qhov sib txawv ntawm lawv cov x-coordinates. Xaiv ob qho ntsiab lus ntawm kab uas haum tshaj plaws. Cov ntsiab lus no yuav lossis tsis yog qhov tseeb tawg cov ntsiab lus ntawm kab. Rho tawm thawj lub ntsiab lus y-koom ua ke los ntawm tus lej thib ob y-koom tes.
Kuj paub yog, koj yuav pom qhov nqes hav sib piv li cas?
Nqes hav feem pua yog xam ntau yam tib yam li cov gradient. Hloov qhov nce thiab khiav mus rau tib chav nyob thiab tom qab ntawd faib qhov nce los ntawm kev khiav. Muab tus lej no los ntawm 100 thiab koj muaj feem pua nqes hav . Piv txwv li, 3 "nce faib los ntawm 36" khiav =.083 x 100 = 8.3% nqes hav.
Koj pom koj cuam tshuam li cas?
Txhawm rau nrhiav y tiv siv kab zauv ntawm kab, ntsaws 0 rau x sib txawv thiab daws rau y . Yog hais tias qhov sib npaug tau sau rau hauv txoj kab nqes hav- cuam tshuam daim ntawv, ntsaws rau hauv txoj kab nqes thiab x thiab y kev sib koom ua ke rau ib qho taw tes ntawm kab los daws rau y.

Dab tsi yog qhov sib txawv ntawm squamous yooj yim thiab yooj yim cuboidal thiab columnar yooj yim?
Piv txwv li, yooj yim squamous epithelial cov ntaub so ntswg piav qhia ib txheej ntawm cov cell uas tiaj thiab nplai zoo li cov duab. Cuboidal epithelium muaj cov cell uas nws qhov siab thiab dav yog kwv yees tib yam. Columnar epithelium muaj cov cell siab dua li lawv dav
Txoj hauv kev yooj yim tshaj plaws los ntxuav lub teeb yog dab tsi?
Ua ntej, ntxuav lub taub hau nrog Windex lossis xab npum thiab dej. Tom qab ntawd, siv daim ntaub mos muag, txhuam tus ntiv tes kom ntau ntawm cov tshuaj txhuam hniav mus rau lub teeb taws ntub. (Tshuaj txhuam hniav nrog baking soda ua haujlwm tau zoo tshaj plaws.) Pib txhuam
Dab tsi yog qhov yooj yim axioms ntawm kev xaiv txoj kev xav?
Kaum Axioms ntawm Kev Xaiv Txoj Cai Tib neeg nkaus xwb uas nws tus cwj pwm peb tuaj yeem tswj hwm yog peb tus kheej. Txhua yam peb muab tau rau lwm tus yog cov ntaub ntawv. Tag nrho cov teeb meem puas siab puas ntsws ntev yog teeb meem kev sib raug zoo. Teeb meem kev sib raug zoo ib txwm yog ib feem ntawm peb lub neej tam sim no
Dab tsi yog x cuam tshuam hauv daim ntawv nqes hav cuam tshuam?
Peb tuaj yeem siv daim ntawv nqes hav-intercept (y = mx + b). Qhov kev cuam tshuam x yog pom los ntawm kev teeb tsa y = 0, vim qhov ntawd yuav ua rau peb x-tus nqi uas cov kab hla ntawm x-axis
Vim li cas lub tswv yim yooj yim tshaj plaws rau kev haus cawv ntxiv?
Lub tswv yim yooj yim tshaj plaws rau kev haus cawv ntxiv yog kom tsis txhob muaj xwm txheej uas muaj cawv vim tias koj tsis tuaj yeem raug ntxias kom haus cawv yog tias tsis muaj
