Tom wasn’t at home yesterday. He went to the park with his grandma. His grandma said, “This park is big and beautiful now. It was old and small then.” Tom said, “Yes, it is beautiful. I want to play in this park!” They walked for half an hour, and Grandma saw her old friend Nina. They talked and had a great time.

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
