2013年新gre考試:gre數(shù)學(xué)考點(diǎn)之Polynomials

字號(hào):


    今天針對(duì)新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,突破新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.
    俗話說:“工欲善其事必先利其器”。有一部分考生認(rèn)為新GRE數(shù)學(xué)具有一定的難度,這其中的原因是由于考生在復(fù)習(xí)時(shí)沒有把新gre數(shù)學(xué)的基礎(chǔ)打牢。想要新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)。
