2011新gre考試實(shí)施以來(lái),不僅對(duì)寫(xiě)作部分茫然不知所措,就連我們所擅長(zhǎng)的數(shù)學(xué)也甚是擔(dān)憂,相信這其中的原因還是由于考生在新gre數(shù)學(xué)復(fù)習(xí)時(shí)沒(méi)有把基礎(chǔ)打牢。如果新版gre數(shù)學(xué)基本考點(diǎn)都沒(méi)有復(fù)習(xí)到,如何能拿到分?jǐn)?shù)呢?所以說(shuō),想要新版gre數(shù)學(xué)考好,復(fù)習(xí)的時(shí)候一定要把基本概念和重要考點(diǎn)都弄扎實(shí)。
今天針對(duì)新版gre數(shù)學(xué)復(fù)習(xí),小編給大家整理的是關(guān)于Polynomials的相關(guān)內(nèi)容,這些概念在考試中一定會(huì)考到的。希望考生能再接再厲,取得一個(gè)好成績(jī),突破新版gre數(shù)學(xué)難的困境。
Polynomials
Any expression with one or more terms is called polynomial.
Example:
3x+2,4x2-x+2,and 4x+3xy+y2are all polynomials.
(3x+5/(2x+y))and sin(3x+2) are not polynomials.
Remember:
Order of a polynomial is the highest power of any variable.
The highest power in an n-th order polynomial is n.
Both monomials and binomials are polynomials of order 1 and 2, respectively.
由于美國(guó)數(shù)學(xué)基礎(chǔ)教育的難度增加導(dǎo)致數(shù)學(xué)考試越來(lái)越難,但新gre數(shù)學(xué)復(fù)習(xí)考點(diǎn)都是高中時(shí)候?qū)W到的知識(shí)點(diǎn),考生不要過(guò)于緊張,把基本概念弄明白,再記住一些新版gre數(shù)學(xué)必備的詞匯,那么相信新版gre數(shù)學(xué)應(yīng)該沒(méi)有問(wèn)題。
