I am Li Yan. Today is Saturday. I go to Lisa's shop. There are many beautiful clocks in her shop. I want to buy a blue one. But it is too expensive. It is 120 yuan.I only have 70 yuan. At last，I buy a yellow one. It is 55 yuan. I like it，too. It can make me get up early in the morning. Do you have a clock?

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
