Yuav Ua Li Cas Sau Cov Lus Taw Qhia rau Kev Sau Ntawv Sau
- Qhia lub ntsiab lus: Cov lus taw qhia yuav tsum qhia lub ntsiab lus uas koj yuav tau hais hauv tsab ntawv thiab muab qee qhov keeb kwm yav dhau los.
- Teem lub suab nrov / txhais cov neeg tuaj saib: Kev taw qhia yog thawj qhov uas tus nyeem yuav pom thiab yuav tsum tsim lub suab uas koj yuav siv thoob plaws hauv tag nrho cov ntawv sau.
Tsis tas li ntawd, ib qho piv txwv ntawm synthesis yog dab tsi? A synthesis Cov tshuaj tiv thaiv tshwm sim thaum ob los yog ntau dua reactants sib xyaw ua ib yam khoom. Ib piv txwv ntawm a synthesis Cov tshuaj tiv thaiv yog kev sib xyaw ntawm sodium (Na) thiab chlorine (Cl) los tsim sodium chloride (NaCl). Cov tshuaj tiv thaiv no yog sawv cev los ntawm kev sib npaug tshuaj: 2Na + Cl2 → 2 NaCl.
Ib yam li ntawd, vim li cas kev sib txuas tseem ceeb hauv kev sau ntawv?
Kev sau ntawv ib daim ntawv tshawb fawb muaj zog yuav tsum muaj peev xwm ua ke -los yog muab cov ntsiab lus ntawm ntau qhov chaw-los pab koj ua qhov taw tes. Lub hom phiaj ntawm Ntau Qhov Chaw Essay yog muab sijhawm rau cov tub ntxhais kawm los xyaum cov txheej txheem ntawm " synthesis ".
Dab tsi yog qhov sib xyaw ua ke hauv kev sau ntawv?
A synthesis yog ib qho kev sib tham uas sau los ntawm ib lossis ntau qhov chaw. Nws ua raws li koj lub peev xwm sau cov syntheses nyob ntawm koj lub peev xwm los txheeb xyuas kev sib raug zoo ntawm cov peev txheej - sau ntawv, kab lus, ntawv tseeb, thiab cov ntawv tsis sau, xws li kev qhuab qhia, kev xam phaj, kev soj ntsuam.

Vim li cas koj thiaj siv cov ntawv sau ua haujlwm?
Function notation yog ib txoj hauv kev los sau cov haujlwm uas yooj yim nyeem thiab nkag siab. Kev ua haujlwm muaj qhov sib txawv thiab muaj kev ywj pheej, thiab thaum peb siv cov cim kev ua haujlwm, qhov kev hloov pauv ywj pheej feem ntau yog x, thiab qhov sib txawv ntawm qhov sib txawv yog F (x). Function notation yog ib txoj kev sib txawv ntawm kev sau ntawv kev sib raug zoo, ok
Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Koj puas siv cov lus qhia hauv kev sau ntawv sau?
Tsab ntawv no yog ntsuas koj lub peev xwm los tsim qhov kev sib cav uas siv cov peev txheej. Yog tias koj siv cov ntaub ntawv los ntawm cov peev txheej, koj yuav tsum sau nws. Yog tias koj nqa cov ntawv tawm ntawm qhov chaw, koj yuav tsum muab tso rau hauv cov lus hais. Tom qab koj hais los yog piav ib qhov chaw, hais nws raws li koj xav tau hauv ib daim ntawv: (Source F) lossis (Gilman)
Yuav ua li cas koj sau txoj kab nqes nqes intercept daim ntawv nyob rau hauv tus qauv daim ntawv?
Standard form yog lwm txoj hauv kev los sau daim ntawv nqes hav-intercept (as opposed to y=mx+b). Nws sau li Ax+By=C. Koj tuaj yeem hloov daim ntawv nqes hav-intercept rau cov qauv zoo li no: Y=-3/2x + 3. Tom ntej no, koj cais qhov y-intercept (qhov no nws yog 2) zoo li no: Ntxiv 3/2x rau txhua sab ntawm kab zauv kom tau qhov no: 3/2x + y = 3
