求y=sin(2x+π/3)的单调增区间求y=sin(2x+π/3)的单调增区间求y=sin(2x+π/3)的单调增区间增区间是:2kπ-π/2≤2x+π/3≤2kπ+π/2即:kπ-5π/12≤x≤

求 y=sin(2x+π/3)的单调增区间
求 y=sin(2x+π/3)的单调增区间

求 y=sin(2x+π/3)的单调增区间
增区间是:2kπ-π/2≤2x+π/3≤2kπ+π/2
即:kπ-5π/12≤x≤kπ+π/12
增区间是:[kπ-5π/12,kπ+π/12],k∈Z

-5π/12+kπ≤x≤π/12+kπ,k属于正整数

-π/2+2kπ≤2x+π/3≤π/2+2kπ
解得-5π/12+kπ≤x≤π/12+kπ;k∈Z
