My name is Alex. Last Monday, I was bored. I had an idea. I went to Hangzhou and visited my uncle. He worked on a farm. He took care of the sheep. I went there by bus. I played with my cousin on the first day. The next day, we went swimming and took many pictures. I stayed in Hangzhou for five days. I ate some fresh food and bought gifts for my parents.

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
