My uncle and aunt invited us to Beijing to have a trip. So my family will leave for Beijing tomorrow. It’s five thousand and one hundred kilometers from my city to Beijing. It’s very far. We are going there by plane and arrive at 7:00 in the evening. We need jackets, sweaters and coats. But I don’t like these sweaters. They are too old. We are going to visit Tian’anmen Square, the Palace Museum, Summer Palace. I am very excited now.

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
