Last year, my father got a new job in Guangzhou. My mother and I moved to live with dad in Guangzhou, and we had our first Spring Festival in Guangzhou. Before the festival, we cleaned our house and decorated(装饰) it with some pictures. One of dad’s friends gave us a small orange tree. We put it in the living room. On New Year’s Eve, we had a big dinner. After dinner, my parents prepared some red envelopes. We call them “lucky money”. During Spring Festival, when a child said “Happy New Year” to them, they gave him or her a red envelope. It is really interesting.

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
