How are you? Do you want to visit my hometown in July? There are lots of mountains near my village. My village is very beautiful in spring. And the mountains become green then. There is a clean river. And there are many trees and flowers by the river. You can see some ducks and many fish swimming in the clean river. It’s not hot there in summer. It’s cool. So I like summer best. Do you like my village? Please come to my village soon.
Yours,
Jack

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
