Kev daws teeb meem. Lo lus teb yog no. Txij li qhov dim P3(R)=4, tsis muaj cov txheej txheem ntawm peb lub npe tuaj yeem tsim tag nrho P3(R).
Ua cov polynomials ncua P3?
Yes! Lub teeb spans qhov chaw yog thiab tsuas yog hais tias nws muaj peev xwm daws tau rau,,, thiab nyob rau hauv cov nqe lus ntawm ib tug lej, a, b, c, thiab d. Tau kawg, kev daws qhov kev sib npaug ntawm qhov kev sib npaug tuaj yeem ua tiav raws li lub matrix ntawm coefficients uas tau txais txoj cai rov qab rau koj txoj kev!
P3 polynomial yog dab tsi?
A polynomial hauv P3 muaj qhov form ax2 + bx + c rau qee qhov tsis tu ncua a, b, thiab c. Xws li ib tug polynomial belongs rau subspace S yog a02 + b0 + c=a12 + b1 + c, los yog c=a + b + c, or0=a + b, los yog b=−a. Yog li cov polynomials hauv subspace S muaj daim ntawv a(x2 −x)+c.
Yuav tau 3 vectors span P3?
(d) (1, 0, 2), (0, 1, 0), (−1, 3, 0), thiab (1, −4, 1). Yog lawm. Peb ntawm cov vectors no yog linearly ywj siab, yog li lawv span R3. … Cov vectors no yog linearly ywj siab thiab ncua P3.
P3 R yog dab tsi?
2. (20) S 1, t, t2 yog tus qauv hauv paus ntawm P3, qhov chaw vector ntawm polynomials ntawm degree 2 lossis tsawg dua.

Los ntawm cov khoom tsim thaum lub sij hawm tsim cov bakelite yog?
Nyob rau hauv rooj plaub ntawm bakelite phenol thiab formaldehyde condense los tsim cov monomer muab H2O raws li cov khoom lag luam. Bakelite tseem hu ua co-polymer. Cov tshuaj tiv thaiv: Phenol reacts nrog formaldehyde los tsim o-Hydroxy methyl phenol.
Puas polynomials yuav tsum muaj exponents?
A polynomial tuaj yeem muaj qhov tsis tu ncua, hloov pauv thiab exponents, tab sis tsis txhob faib los ntawm qhov sib txawv. Tsis tas li ntawd lawv tuaj yeem muaj ib lossis ntau cov ntsiab lus, tab sis tsis yog tus lej tsis kawg. Pob polynomials ib txwm muaj exponents?
Yuav faib cov polynomials los ntawm binomials li cas?
Long Division of a Polynomial by a Binomial Faib qhov siab tshaj plaws ntawm lub sijhawm ntawm lub npe los ntawm lub sijhawm siab tshaj plaws ntawm lub binomial. … Muab qhov txiaj ntsig no los ntawm kev faib, thiab rho tawm cov txiaj ntsig binomial los ntawm polynomial.
Nyob rau hauv cov kev tsim tawm no suav nrog kev tsim cov gemmule?
C) Asexual reproduction tshwm sim nyob rau hauv spongilla los ntawm kev loj hlob ntawm gemmules. Spongilla belongs rau Porifera Porifera Ib daim txhuam cev yog ib qho cuab yeej lossis kev pab tu ua los ntawm soft, porous khoom. Feem ntau siv los ntxuav qhov chaw impervious, sponges yog tshwj xeeb tshaj yog zoo ntawm absorbing dej thiab dej raws li kev daws teeb meem.
Puas yog cov nroj tsuag carnivorous yog cov tsim khoom lossis cov neeg siv khoom?
As producers, cov nroj tsuag tsim lub hauv paus ntawm yuav luag txhua cov khoom noj hauv ntiaj teb. Carnivorous nroj tsuag zoo li "tig rooj" thaum lawv ua raws li cov neeg siv khoom, gobbling kab, qav, thiab cov tsiaj me me. Puas yog Venus flytrap yog tus neeg siv khoom thiab tsim khoom?
