My name is Su Nan. I live in Sanya. It's a beautiful city. The weather is very hot in summer. But I often go swimming on a hot day. We can eat delicious food, too. In winter, the weather is not cold. It's often cool. We can wear our shirts and coats. People like to visit here in this season. There are some places of interest in Sanya. They are Tianya Haijiao and Wuzhizhou Island（支洲岛）. I love Sanya. What about you?

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
