Cov Interrupted Goode Homolosine projection ( Goode tus ) yog ib cuam tshuam , pseudocylindrical, sib npaug - cheeb tsam , composite map qhov projection uas tuaj yeem nthuav qhia tag nrho lub ntiaj teb ntawm ib daim ntawv qhia. Cov av loj thoob ntiaj teb tau nthuav tawm nrog lawv thaj chaw nyob rau hauv kev faib ua feem, nrog tsawg heev cuam tshuam , thiab tsawg kawg tag nrho distortion.
Ntawm no, Goode qhov kev cuam tshuam sib npaug thaj tsam li cas?
Cov Goode homolosine qhov projection (los yog cuam tshuam Goode homolosine qhov projection ) yog pseudocylindrical, sib npaug - cheeb tsam , composite map qhov projection siv rau daim ntawv qhia ntiaj teb. Feem ntau nws tau nthuav tawm nrog ntau yam cuam tshuam. Nws sib npaug - cheeb tsam cov cuab yeej ua rau nws muaj txiaj ntsig zoo rau kev nthuav tawm spatial faib ntawm cov xwm txheej.
Kuj Paub, qhov sib npaug cheeb tsam projection yog dab tsi? Ib vaj huam sib luag projection yog ib daim ntawv qhia qhov projection uas qhia cov cheeb tsam uas loj tib yam hauv lub ntiaj teb qhov loj tib yam ntawm daim ntawv qhia tab sis tej zaum yuav cuam tshuam cov duab, lub kaum sab xis, thiab / lossis nplai.
Tib neeg kuj nug, dab tsi yog qhov zoo ntawm kev siv Goode's interrupted vaj huam sib luag daim duab qhia chaw?
Xyoo 1923, J. Paul Goode Kev sib koom ua ke ntawm Mollweide (homolographic) qhov projection thiab Sinusoidal qhov projection tsim Goode tus Homolosine cuam tshuam . Cov qhov zoo ntawm no qhov projection yog txhua tus continents yog qhov loj thiab nyob rau hauv kev faib ua feem rau ib leeg. Cov qhov tsis zoo yog nrug thiab kev taw qhia tsis raug.
Vim li cas Paul Goode cuam tshuam nws qhov kev kwv yees Homolosine?
Cov projections cuam tshuam yog li ntawd cov av loj (tshwj tsis yog Antarctica) lossis dej hiav txwv yog txuas. Tag nrho cov latitudes yog kab ncaj. Nyob ntawd yog rau txoj kab ncaj longitude vim qhov cuam tshuam xwm ntawm qhov projection.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Dab tsi ua rau txoj kev xav zoo ib qho kev xav zoo txog kev puas siab puas ntsws?
Ib txoj kev xav zoo yog kev sib koom ua ke - nws piav qhia ntau qhov tseeb thiab kev soj ntsuam hauv ib qho qauv lossis lub hauv paus. Txoj kev xav yuav tsum yog nyob rau hauv ib yam. Ib txoj kev xav zoo yuav tsum ua qhov kev kwv yees uas tuaj yeem kuaj tau. Qhov ntau meej thiab "tseem ceeb" qhov kev xav ntawm kev kwv yees yog - qhov ntau nws nthuav tawm nws tus kheej mus rau kev dag
Nws puas yuav ua rau pom qhov sib npaug ntawm kab sib npaug mus rau ib kab thiab los ntawm ib qho taw tes ntawm kab?
Qhov sib npaug ntawm ib kab uas yog parallel lossis perpendicular rau ib kab? Cov lus teb tau: Cov nqes hav ntawm cov kab sib npaug sib npaug. Hloov txoj kab nqes paub thiab cov kev sib koom ua ke ntawm ib qho taw tes ntawm lwm txoj kab rau hauv daim ntawv point-slope kom pom qhov sib npaug ntawm kab sib npaug
Puas yog nws ua tau rau ib qho kev sib npaug ntawm ob txoj kab sib npaug kom tsis muaj kev daws teeb meem piav qhia koj qhov laj thawj?
Cov kab ke ntawm kab sib npaug tuaj yeem tsuas muaj 0, 1, lossis ib qho kev daws teeb meem tsis kawg. Ob kab no tsis tuaj yeem hla ob zaug. Cov lus teb raug yog tias qhov system muaj ib qho kev daws teeb meem. Total Number of Points Number of 2-Point Baskets Number of 3-Point Baskets 17 4 (8 ntsiab lus) 3 (9 points) 17 1 (2 points) 5 (15 points)
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
