Dear Grandma,
How are you? Thank you for the new shirt. It’s beautiful. I like it. Now I am writing (写) at the new school. This is a nice school. The trees are green, the flowers are red and yellow. We have a music room, an art room, a computer room, a canteen and a library. The playground is so big. We can play football there.
Oh, it’s time to go home now. Let me stop here. Welcome to my school and welcome to my home.

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
