Dear Xiao Ming, How are you doing? I am writing to ask you something about the Chinese Culture Week that we are going to hold in September. As the chairman of the Chinese Learning Club at school,I am thinking about how we can organize a unique and amazing activity. Therefore,could you please give me some good suggestions on what theme might be better and what exactly we are going to do?Thanks. Sam |
It's a good idea to have such a Culture Week in your school. __________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
Xiao Ming同类型试题
y = sin x, x∈R, y∈[–1,1],周期为2π,函数图像以 x = (π/2) + kπ 为对称轴
y = arcsin x, x∈[–1,1], y∈[–π/2,π/2]
sin x = 0 ←→ arcsin x = 0
sin x = 1/2 ←→ arcsin x = π/6
sin x = √2/2 ←→ arcsin x = π/4
sin x = 1 ←→ arcsin x = π/2
