Dear Mom,
How are you? The weather here was cool and dry yesterday, but it’s hot and wet today. My clothes were clean this morning, but I played outside, so they are dirty now. Do you like this building? It is a museum in Guangzou, I visited yesterday.
Bye bye,
Gogo

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
