1-5CCDBB 6-10 CAACC 11-15 CDBDB （16）COS派除以2010 （17）負(fù)一
（18）16 （19）四分之一 （20）三分之一
21.∵a平行于b ∴2*1/6-sinα*cosα=0 ∴（sin2α）/2=1/3 ∴sin2α=2/3
22.因?yàn)閍2=2,a4=8所以a1乘q=2,a1乘q得三次方=8,所以q方=4所以q=2,a1=1,所以sn=2得n次方-1
23題：因?yàn)檎叫蜛BCD 又因?yàn)锳BCD－A1B1C1D1是長方體 所以AC垂直BD D1D垂直面ABCD B1B垂直面ABCD 所以B1B垂直AC D1D垂直AC 因?yàn)锳C垂直BD 所以AC平面B1BD1D
24：一共有6種,以下為（1,2）（1,3）（1,4）（2,3）（2,4）（3,4） 均為奇數(shù)的概率為1/6 同為奇數(shù)或同為偶數(shù)的概率為1/3
25（1）要有不相等兩實(shí)數(shù)根則 △=b方減4ac 有因?yàn)閍+b+c=0 所以b=負(fù)a-c 所以b方減4ac=（負(fù)a-c）方-4ac=a方加2ac加c方減4ac=a方減2ac加c方=（a-c）方 又因?yàn)閍>c 所以△大于0 所有有兩個(gè)不相等的實(shí)數(shù)根
