Yog li ntawd, hom duab twg siv rau cov ntaub ntawv txuas ntxiv?
Kab Daim duab Ib kab daim duab nthuav tawm cov ncauj lus lossis kev ua haujlwm dhau sijhawm thiab tuaj yeem ua tau siv los qhia ntau yam sib txawv ntawm cov ntaub ntawv . Koj yuav tsum siv nws thaum koj daim duab a cov ntaub ntawv txuas ntxiv teeb.
Tsis tas li ntawd, 3 hom kab kos yog dab tsi? Muaj ntau qhov sib txawv hom ntawm kab kos thiab daim duab . Plaub feem ntau yog tej zaum kab daim duab , bar daim duab thiab histograms, ncuav qab zib kab kos, thiab Cartesian daim duab . Lawv feem ntau siv rau, thiab zoo tshaj plaws rau, ntau yam sib txawv.
Ib yam li ib tug yuav nug, hom duab twg yuav pab tau rau kev sib piv cov ntaub ntawv ntau?
Qhov no hom duab yog siv nrog quantitativedata . Qhov ntau ntawm qhov tseem ceeb, hu ua chav kawm, tau teev nyob rau hauv qab, thiab cov chav kawm uas muaj ntau zaus muaj cov kab siab dua. Ib histogram feem ntau zoo li ib qho bar daim duab , tab sis lawv txawv vim hais tias ntawm qib ntsuas ntawm lub cov ntaub ntawv.
Dab tsi yog hom kab graphs sib txawv?
Hom sib txawv ntawm Cov duab Lub yim hom yog kab tawm , hwj chim, plaub fab, polynomial, rational, exponential, logarithmic, thiab sinusoidal.

Dab tsi scatter zaj duab xis qhia tau hais tias muaj kev sib raug zoo tsis zoo?
Nws yog tseeb los ntawm scatterplot tias y txo qis li x nce. Peb hais tias muaj kev sib raug zoo tsis zoo nyob nruab nrab ntawm qhov sib txawv x thiab y. Xav txog cov nram qab no scatterplot: Peb saib tias y nce li x nce, thiab cov ntsiab lus tsis nyob ntawm txoj kab ncaj nraim
Vim li cas nws thiaj li hais tias lub Orthocenter ntawm daim duab peb sab obtuse yuav tsum nyob rau sab nraud ntawm daim duab peb sab?
Nws hloov tawm tias tag nrho peb qhov siab ib txwm sib tshuam ntawm tib lub ntsiab lus - lub npe hu ua orthocenter ntawm daim duab peb sab. Lub orthocenter tsis yog ib txwm nyob hauv daim duab peb sab. Yog tias daim duab peb sab yog obtuse, nws yuav nyob sab nraud. Txhawm rau ua kom qhov no tshwm sim cov kab qhov siab yuav tsum tau txuas ntxiv kom lawv hla
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
Lub hauv paus ntsiab lus Aufbau ua haujlwm li cas uas txhais tau hais tias orbitals tau sau los ntawm hauv qab los yog saum toj saud nyob ntawm daim duab)?
Los ntawm Hauv qab Up: Cov chav yuav tsum tau sau los ntawm hauv av pem teb mus rau. Hauv pem teb siab dua qhov kev txiav txim yuav hloov me ntsis. Aufbau Txoj Cai: cov electrons sau cov orbitals ntawm lub zog qis tshaj mus rau lub zog siab tshaj. Nyob rau hauv lub xeev av tag nrho cov electrons nyob rau hauv qis tshaj tau lub zog theem
Yam dab tsi ntawm cov dej zoo tshaj plaws piav qhia nws lub peev xwm los yaj ntau yam khoom siv?
Vim tias nws cov polarity thiab muaj peev xwm tsim cov ntawv cog lus hydrogen, dej ua rau cov kuab tshuaj zoo heev, txhais tau tias nws tuaj yeem yaj ntau hom molecules
