It’s a sunny day. I go to Xiamen by plane with my parents and friends. We go to the island(岛) by boat. There are many big trees on the island. There are many houses with red roofs. I swim in the sea with my parents. We play on the beach. Then we eat much food such as(比如) fish and pie. The pie is sweet and soft. We enjoy ourselves very much. How happy we are!

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
