（理科）对于函数f（x）=sinx，g（x）=cosx，h（x）=x+π3

（理科）对于函数f（x）=sinx，g（x）=cosx，h（x）=x+π3

由于f（x）-g（x）=sinx-cosx=2sin（x-π4），故它的最大值等于2，故（1）正确．由于f[h（x）]=sin[（h（x）]=sin（x+π3），当 x∈[-π2，0]时，（x+π3）∈[-π6，π3]?[-π2，π2]，故f[h（x）]在区间[-π2，0]...======以下答案可供参考======供参考答案1:Buddhists, not the same level of learning, understanding of the Buddhist also different. Where is the significance of a Buddhist? Many people, learn just to ensure peace, security rich, healthy, with this purpose to a large number of Buddhists.
