Last Sunday it was sunny. Tony, Tim and Peter went to have a picnic in the park. Tony took his football and skating shoes. Peter took his swimsuit. Tim took his robot. They played games under a tree. They sang and danced. And then they were hungry and thirsty. Tony ate many oranges. Then he had a stomach ache. Peter swam in the sea, and then he had a fever. Tim fell down and bumped his arm. Tim’s brother Simon took them to the hospital.

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
