由于美国数学基础教育的难度增加,gre数学考试也越来越难,所以新版gre数学部分不能轻视,以下是小编为大家搜索整理的有关新版gre数学中常考知识:代数和几何部分。
代数和几何部分知识点:
1.正整数n有奇数个因子,则n为完全平方数
2.因子个数求解公式:将整数n分解为质因子乘积形式,然后将每个质因子的幂分别加一相乘.n=aaabbc则因子个数=
eg. 200=222 55 因子个数==12个
3.能被8整除的数后三位的和能被8整除;能被9整除的数各位数的和能被9整除.能被3整除的数,各位的和能被3整除.
4.多边形内角和=x180
5.菱形面积=1/2 x 对角线乘积
6.欧拉公式:
边数=面数+顶点数-2
8.三角形余玄定理
C2=A2+B2-2ABCOS,为AB两条线间的夹角
9.正弦定理:A/SinA=B/SinB=C/SinC=2R
10.Y=k1X+B1,Y=k2X+B2,两线垂直的条件为K1K2=-1
11.N的阶乘公式:
N!=123....N 且规定0!=1 1!=1
Eg:8!=12345678
12. 熟悉一下根号2、3、5的值
sqrt=1.414 sqrt=1.732 sqrt=2.236
13. ...2/3 as many A as B: A=2/3B
...twice as many... A as B: A=2B
14. 华氏温度与摄氏温度的换算
换算公式F-32)5/9=C
PS.常用计量单位的换算自己查查牛津大字典的附录吧)
