高一数学口算题100道

1,在递增等差数列{an}中,已知a4=-3,且a1-2、a3、a5成等比数列,n属于N*,(1)求数列{an}的公差d(2)设5数列{an}的前n项和为Sn,求Sn的最值

2,在三角形ABC中,已知向量AB*向量AC=1,向量AB*向量BC=-2(1)求AB的长度;(2)证明:tanA=2tanB;(3)若│向量AC│=2,求│向量BC│(││为绝对值符号)

3.函数f(x)=(cosx)^4-(sinx)^4+1的最小正周期为?

4.函数y=5*根号内(x-1)+根号内(10-2x)的最大值为?

要解题)过程哦.

1. (1) A4=A1+3d=-3,A1=-3(1+d)…①,(A1-2)(A1+4d)=(A1+2d)²…②, 由①,②解得d=1(∵ d>0)

(2) ∵ A1=-3-3d=-6<0,d=1>0, ∴ Sn有最小值, 由An=n-7≤0,

A(n+1)=n-6≥0,得6≤n≤7, ∴ n=6获,即数列{an}的前6项或7项的和最小,最小值为S6=S7=(-6)×6+6×5/2=-21

2. (1) 设A(0,0,B(a,0),C(c,b),则向量AB=(a,0), 向量AC=(c,b), 向量BC=(c-a,b). ∵ (a,0)(c,b)=1, (a,0)(c-a,b)=-2, 解得a²=3, ∴ |AB|=|a|=√3

(2) cosA=1/(|AB||AC|),cos(π-B)=-2/(|AB||BC|),0.5|AB||AC|sinA=0.5|AB||BC|sinB===>tanA=2tanB

(3) cosA=1/(2√3),由余弦定理,得|BC|²=5, ∴ |BC|=√5

3. f(x)=(cosx)^4-(sinx)^4+1=(cos²x+sin²x)(cos²x-sin²x)+1

=1+cos2x, ∴ 最小正周期T=π

4. ∵ 定义域x∈[1,5]. ∴ -1≤(x-3)/2≤1,

y²=23x-15+20√2√[1-(x-3)²/4],设x-3=2sinθ,则x=3+2sinθ,

-π/2≤θ≤π/2, y²=23(3+2sinθ)-15+20√2cosθ=46sinθ+20√2cosθ+54=54sin(θ+φ)+54(其中tanφ=10√2/23), ∵ sin(θ+φ)≤1,

∴ y²≤108, y≤6√3,最大值为6√3

高一数学题解题思路

解法一:

设Z....... 抽到中行卡

设J....... 抽到建行卡

设N.......抽到农行卡

设G......抽到工行卡

P(Z)=1/3,

P(J)+P(N)=5/12

P(G)+P(N)=5/12

P(Z)+P(J)+P(G)+P(N)=1

解得

P(J)=P(G)=1/4

P(N)=1/6

解法二:

从中任取一张,得到中行卡的概率是1/3,说明:中行卡数=4

得到建行卡或农行卡的概率是5/12,可知:建行卡数+农行卡数=5

得到农行卡或工行卡的概率是5/12,可知:工行卡数+农行卡数=5

中行卡数+建行卡数+农行卡数+工行卡数=12

解得:建行卡数=工行卡数=3,农行卡数=2

由此可得得到建行卡,农行卡和工行卡的概率分别为1/4,1/6,1/4

高二数学计算题100道及答案

中行卡的概率是1/3,其他卡的概率是1-1/3=2/3,由于建行卡或农行卡的概率是5/12所以工行卡的概率就是2/3-5/12=8/12-5/12=3/12=1/4,由于农行卡或工行卡的概率是5/12,建行卡的概率就是2/3-5/12=8/12-5/12=3/12=1/4,因此农行卡的概率就是2/3-1/4-1/4=2/12=1/6。因此 建行卡,农行卡和工行卡的概率分别为1/4,1/6,1/4

tan六分之十七π=tan六分之七π=tan六分之π=三分之根号三

以上就是高一数学计算题100道的全部内容,解答题先解不等式求出集合B再根据A是否为空集讨论 过程如下:计算题(1)根据对数的性质变形,化简结果=2(2)通分,平方差公式,完全平方公式结果=2(a+b)/(a-b)过程如下:提问者评价 太给力了。
