A New Beautiful Park
There is a new park near my house. It is so beautiful that we like it very much. It’s a fine day today. My family and I are in the park now. On my left there is a big tree. On my right, there is a big lake. There are many flowers and trees near the lake. This is a small hill behind the big lake. Near the lake, there is a sign: “ Don’t swim in the lake!” some children are playing beside the lake. Their parents are looking after them carefully. Look, a boy is trying to step into the water, it’s dangerous to do this, They should stay away from water.

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
