新GRE數(shù)學(xué)考試的其中一個考點是交集和并集,為了幫助考生能夠更好的掌握這個GRE數(shù)學(xué)的重要考點,下面澳際教育小編就給大家詳細的講解一下這個新GRE數(shù)學(xué)考試的考點。   對于數(shù)學(xué)中的并集和交集,我們并不陌生,在GRE數(shù)學(xué)考試中,也有這一考查內(nèi)容。本文澳際教育GRE考試頻道為大家介紹的是GRE數(shù)學(xué)復(fù)習(xí)考點“并集和交集”。   新GRE數(shù)學(xué)復(fù)習(xí)重要考點:Intersection of Sets交集   Intersection of two sets is another set with only the members that are in both sets. If the two sets do not share any common member, the intersection is the empty set with no member.   Example:   Intersection of {1,2,3} and {2,3,5} is the set {2,3}.   Intersection of the set with all primes and the set with all even numbers is the set {2} since only 2 is both even and prime.   Intersection of {1,2,3} and {4,5,6} is the empty set {}.   Remember:   Intersection contains only the common members.   Two sets are disjoint if they have no member in common, that is they have an empty intersection.   新GRE數(shù)學(xué)復(fù)習(xí)重要考點:Union of Sets 并集   Union of two sets is another set with all the members from both sets.   Example:   Union of {2,3,5} and {1,3,4} is the set {1,2,3,4,5}.   Union of {1,2,1} and {1,2} is the set {1,2,1}.   Remember:   The common members do not repeat in the union.   本文針對新GRE數(shù)學(xué)考試的交集和并集考點進行了詳細的解析,考生在復(fù)習(xí)新GRE數(shù)學(xué)考試的時候,可以通過本文掌握這個考點,希望能夠?qū)Υ蠹业腉RE數(shù)學(xué)考試有所幫助。   澳際六步曲第二步為您進行考試指導(dǎo),澳際培訓(xùn)核心思維顛覆國內(nèi)傳統(tǒng)大班無差異化批發(fā)模式,采取一對一個性化教學(xué),輔之小班精英輔導(dǎo)應(yīng)試方法和學(xué)生英語能力結(jié)合,考試輔導(dǎo)和留學(xué)規(guī)劃一體化行動,學(xué)生國際化英語思維構(gòu)建及西方人文知識和視野的開拓并重。   我們具體的服務(wù)項目如下:   1. 免費測評模考,分析申請人的問題,制作考試測評報告和備考指導(dǎo)   2. 結(jié)合申請人的申請目標和考試基礎(chǔ),制定考試整體規(guī)劃及時間安排   3. 提供對申請人有幫助的考試經(jīng)驗和機經(jīng)等   4. 根據(jù)需要提供免費口語模擬和指導(dǎo)服務(wù)   5. 免費修改作文4篇   6. 考前心理指導(dǎo),調(diào)整考前心理狀態(tài)   (注:口語模擬和作文修改服務(wù)提供時間為每年2月28日-8月1日)
