Today is Sunday. There’re many people in the park. On the hill there’re some apple trees. There’re some birds and some boys in the apple trees. There’s a small boat on the river. Jim and the twins are in it. What’s in Jim’s hand? There’s a white kite. It looks like a bird. Who’s that man in the red car? Oh, that’s our English teacher Mr Brown. He’s American. Can you see Kate? She is behind that tall tree. She wears a green sweater. It looks very nice.

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
