Y=sin(x +π/3)则f(x)的单调增区间
Y=sin(x +π/3)则f(x)的单调增区间

Y=sin(x +π/3)则f(x)的单调增区间
当2kπ-π/2≤x +π/3≤2kπ+π/2,k属于整数时,Y=sin(x +π/3)是增函数,

当2kπ-5π/6≤x ≤2kπ+π/6,k属于整数时,Y=sin(x +π/3)是增函数,
即单调增区间[2kπ-5π/6,2kπ+π/6],k属于整数.

y=sin(x+Pai/3)的单调增区间是:
2kPai-Pai/2<=x+Pai/3<=2kPai+Pai/2
即是【2kPai-5Pai/6,2kPai+Pai/6】

【2kπ-5/6π,2kπ+1/6π】
