My name is Mark. I’m thirteen years old. My favourite festival is Spring Festival. It is in January or February. On the eve of the Spring Festival, we always have a big family dinner. We have dumplings. After dinner, we watch TV together. On the morning of the Spring Festival, we wear new clothes, and people say “Happy New Year” to each other. The children can get lucky money. So they like it very much.

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
