General Note: Polynomials
Lub zog siab tshaj plaws ntawm qhov sib txawv uas tshwm sim hauv lub polynomial yog hu ua degree ntawm a polynomial . Cov coj lub sij hawm yog lub sij hawm nrog lub siab tshaj plaws hwj chim, thiab nws coefficient yog hu ua coj coefficient.
Tsis tas li cov lus nug yog, dab tsi yog qhov ua coefficient hauv polynomial?
SOLUTION: Qhov degree ntawm lub polynomial yog tus nqi ntawm qhov loj tshaj exponent. Cov coj coefficient yog cov coefficient ntawm thawj lub sij hawm ntawm lub polynomial thaum sau ua qauv. Cov coj coefficient yog cov coefficient ntawm thawj lub sij hawm ntawm lub polynomial thaum sau ua qauv.
Ib tug kuj yuav nug, dab tsi yog piv txwv ntawm coefficient? Tus lej siv los muab ntau qhov sib txawv. Piv txwv : 6z txhais tau tias 6 npaug z, thiab "z" yog qhov sib txawv, yog li 6 yog a coefficient . Variables uas tsis muaj tus lej muaj a coefficient ntawm 1. Piv txwv x:1x yog. Qee zaum ib tsab ntawv sawv cev rau tus lej.
Kuj nug, dab tsi yog tus coefficient nyob rau hauv ib tug polynomial?
Hauv lej, a coefficient yog ib qho kev sib txuam hauv qee lub sij hawm ntawm a polynomial , series, lossis ib qho kev qhia; nws feem ntau yog tus lej, tab sis tej zaum yuav yog ib qho kev qhia. Hauv qhov xwm txheej kawg, cov hloov pauv tshwm sim hauv cov coefficients feem ntau hu ua parameters, thiab yuav tsum tau kom meej meej qhov txawv ntawm lwm qhov sib txawv.
Dab tsi yog lub ntsiab lus ntawm kev coj tus coefficient?
Thawj coefficients yog cov lej sau rau pem hauv ntej ntawm qhov sib txawv nrog tus lej loj tshaj plaws. Ib yam li niaj zaus coefficients , lawv tuaj yeem yog qhov zoo, tsis zoo, tiag, lossis kev xav nrog rau tag nrho cov lej, feem ntau lossis lej. Piv txwv li, hauv kab zauv -7x^4 + 2x^3 - 11, qhov siab tshaj plaws exponent yog 4.
Pom zoo:
Thawj degree polynomial yog dab tsi?
Thawj Degree Polynomials. Thawj degree polynomials tseem hu ua linear polynomials. Hauv particular, thawj degree polynomials yog cov kab uas tsis yog kab rov tav lossis ntsug. Feem ntau, tsab ntawv m yog siv los ua tus coefficient ntawm x tsis yog a, thiab yog siv los sawv cev rau txoj kab nqes
3rd degree polynomial yog dab tsi?
Thib peb degree polynomials tseem hu ua cubic polynomials. Cubics muaj cov yam ntxwv zoo li no: Ib mus rau peb lub hauv paus. Ob los yog xoom extrema. Cov hauv paus hniav yog solvable los ntawm radicals
Dab tsi yog qhov sib txawv ntawm lub thawv thiab lub thawv ntawv thiab lub thawv ntawv yog dab tsi?
Ib lub thawv thiab cov ntawv nplawm (qee zaum hu ua boxplot) yog ib daim duab uas nthuav tawm cov ntaub ntawv los ntawm tsib lub ntsiab lus. Nyob rau hauv ib lub thawv thiab whisker zajlus: qhov kawg ntawm lub thawv yog lub sab sauv thiab sab quartiles, yog li lub thawv spans lub interquartile ntau yam. qhov nruab nrab yog cim los ntawm ib txoj kab ntsug hauv lub thawv
Dab tsi yog qhov zoo sib xws thiab qhov txawv ntawm relays thiab PLC yog dab tsi?
Relays yog electro-mechanical keyboards uas muaj coil thiab ob hom kev sib cuag uas tsis yog NO & NC. Tab sis Programmable Logic Controller, PLC yog lub khoos phis tawj me uas tuaj yeem txiav txim siab raws li qhov kev zov me nyuam thiab nws cov tswv yim & tso tawm
Dab tsi yog qhov sib txawv ntawm qhov ntsuas qhov ntsuas thiab qhov ntsuas thib ob?
Primary index: nyob rau hauv ib tug sequentially order file, qhov Performance index uas nws search key qhia cov sequential order ntawm cov ntaub ntawv. Kuj hu ua clustering index. Secondary index: ib qho Performance index uas nws qhov tseem ceeb tshawb nrhiav qhia qhov kev txiav txim sib txawv ntawm qhov kev txiav txim ntawm cov ntaub ntawv. Kuj hu ua non-clustering index
