Dear Lucy,
I'm in Haikou now. I arrived here last Sunday. My grandma and cousin met me at the airport. We took a green taxi to their house.
Haikou is very beautiful. It is very hot. And there are lots of trees and buildings here. Our house is near the sea. It is very big and beautiful. I can swim every day. And I can also eat the fresh fish. I feel very happy.
I love Haikou. I will write again soon.

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
