In Sunday morning, a terrible accident happened to my best friend Tom While he is riding a bike to the supermarket, the car suddenly came out. Tom was listening music on his bike and he didn’t pay attention to the car. Luckily, the driver in the car was such careless that he didn’t stop in time and hit Tom. Tom was badly hurt. When I saw he in the hospital, he regretted what he did in the morning. “Because there are much cars in the street and not every driver follows the rules, so you must be careful when you cross the road.” He said to me. “Safety is the more important thing in life.”

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
