I'm Sam. Today is the Chinese New Year. It's also called the Spring Festival. They have a very big family dinner. They have dumplings and fish. They don't have a Christmas tree, but they have some firecrackers (鞭炮) and lanterns. Daming's parents give him red packets. They love the Spring Festival very much!
Yours,
Sam

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
