Last Saturday, I went to the park with my friends. We went there by bus in the morning. I played football with my friends. We sang and danced. And then we were hungry and thirsty. We drank some juice and ate some bread. In the afternoon, we walked in the park. We saw lots of birds and beautiful flowers. We took many pictures. We went back home at 6:00. We all had a good time.

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
