My friends and I were busy last Saturday. Wang Qiang played with the rabbits in the zoo. Zhang Xi was in a speaking contest. She did very well. She won the first prize. Li Ling was in the library and read books about space. She wanted to be an astronaut. Zhao Gang played football in the park. I saw the robot show in the Science Museum. We all had a great 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
