Amy and her family are in the dinosaur museum. There are many dinosaurs here. Some dinosaurs are bigger than houses. Some are smaller than our schoolbags. There were lots of dinosaurs many years ago. Some of them ate plants. Some of them ran faster, so they could eat other smaller dinosaurs. But we can only see dinosaurs in museums now.

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
