Snakes haven’t got legs or feet. They can’t hear, but they can smell very well. They put out their tongues (舌头) to smell the air. They love the sun. They sleep in winter. Pandas are fat and cute. They are black and white. And they are friendly to people. So people like them very much. Most pandas live in Sichuan. They usually live in the forest of the high mountains. They like to climb the tree. Their favourite food is bamboo. They eat for twelve hours a day. They are our friends, so we should protect (保护) them.

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
