1、章末综合检测(一)(时间:120分钟,满分:150分)一、选择题(本大题共 12 小题,每小题5 分,共 60 分在每小题给出的四个选项中,只有一项是符合题目要求的)1函数 ytan x2是()A最小正周期为4的奇函数B最小正周期为 2的奇函数C最小正周期为 4的偶函数D最小正周期为2的偶函数解析:选 B该函数为奇函数,其最小正周期 T122.2简谐运动 y4sin 5x3的相位与初相是()A5x3,3B5x3,4 C5x3,3D4,3解析:选 C.相位是 5x3,当 x0 时的相位为初相即3.3设 a0,角 的终边与单位圆的交点为P(3a,4a),那么sin 2cos 的值等于()A.25B
2、25C.15D15解析:选 A.因为点 P 在单位圆上,则|OP|1.即(3a)2(4a)21,解得 a15.因为 a0,所以 a15.所以 P 点的坐标为35,45.所以 sin 45,cos 35.所以 sin 2cos 4523525.4设 为第二象限角,则sin cos 1sin21()A1 Btan2Ctan2D1 解析:选 D.sin cos 1sin21sin cos cos2sin2sin cos cos sin.因为 为第二象限角,所以 cos 0,sin 0.所以原式sin cos cos sin sin cos cos sin 1.5已知函数 f(x)sin x2(xR)
