An owl is a bird with very big eyes. These eyes make the owl look clever. The owl can not move its eyes freely as we can. It can only look straight ahead. If it wants to look at both sides, it must turn its neck. Owls see better at night than at day. All night they look for food. They eat mice and insects. Owls make a strange noise. Because the owls sleep most of the day, they usually give out their cries at night. The cry sounds like “Whool! Whool!” This strange sound sometimes frightens people at night.

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
