Hi, I’m Amy. I’m from the UK. But now I’m living in Beijing, China. I went to Sanya with my parents over the winter holiday. I liked it. Because it was so warm. Hainan is far from Beijing. So we went there by plane. The beach was beautiful. I took lots of pictures and I also went swimming.
On the last day, I bought some gifts for my friends.

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
