Last Sunday was a sunny day. In the morning, we went to a nice park. My father rode a bike there. My mother took some pictures of beautiful flowers there. My sister and I played football with each other. I saw some beautiful birds in the tree. They were singing. We ate some delicious food at noon. In the afternoon, we went to the cinema and saw a funny film. In the evening, we bought two hamburgers for grandma, but grandma ate only one. I ate another one. It was delicious!

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
