1．使arcsin(1－x )有意义的x 的取值范围是( )
A ．[1－π，1]
B ．[0,2]
C ．(－∞，1]
D ．[－1,1]
解析：选B 由题知应有－1≤1－x ≤1，∴0≤x ≤2.
2．cos ?
???arcsin 12的值为( ) A. 12
B. 32 C ．－12 D ．－
32 解析：选B ∵在????－π2，π2上，arcsin 12＝π6
， ∴cos ????arcsin 12＝cos π6＝32
. 3．方程cos x ＋
22＝0，x ∈[0,2π]的解集是( ) A. ??????3π4，5π4 B. ????
??－π4，3π4 C. ????
??－π4，－3π4 D. ??????5π4，7π4 解析：选A 在[0,2π]内，cos
3π4＝cos 5π4＝－cos π4＝－22. 4．若tan α＝
33，且α∈????π2，3π2，则α＝( ) A. π6
B. 5π6
C. 7π6
D. 11π6
解析：选C ∵tan π6＝33
，又α∈????π2，3π2， ∴α＝π＋π6＝7π6
. 5．已知sin x ＝－1213
，x ∈????π，3π2，则x 等于( ) A ．arcsin ???
?－1213 B ．π－arcsin 1213 C ．π＋arcsin 1213 D. 3π2－arcsin 1213
解析：选C ∵x ∈????π，3π2，∴x ＝π＋arcsin 1213
. 6．若sin(x －π)＝－22
，且－2π＜x ≤0，则角x ＝________. 解析：∵sin(x －π)＝－sin(π－x )＝－sin x ＝－
22， ∴sin x ＝22.∴x ＝2k π＋π4或2k π＋34
π(k ∈Z)． 又－2π π. 答案：－74π或－54 π 7．若α∈(0,2π)，tan α＝1，cos α＝－22 ，则α＝________. 解析：由已知，得α是第三象限的角．又α∈(0,2π)，tan 5π4＝1，cos 5π4＝－22， ∴α＝5π4 . 答案：5π4 8．已知等腰三角形的顶角为arccos ??? ?－12，则底角的正切值是________． 解析：∵arccos ????－12＝2π3 ， ∴底角为π－2π32＝π6.∴tan π6＝33 . 答案：33 9．求方程tan x ＝－3，x ∈(－π，π)的解集． 解：∵tan ????－π3＝－tan π3 ＝－3， tan ????π－π3＝－tan π3 ＝－3， －π3，π－π3＝2π3 都在(－π，π)内， ∴方程tan x ＝－3，x ∈(－π，π)的解集为???? ??－π3，2π3. 10．已知cos ????2x ＋π3＝－12，x ∈[0,2π]，求x 的集合． Unit 5 Languages Around the World Period One 1.Chinese c__________ are made out of simple basic strokes. 2.
