Dear friend,
My name is Peter. I am 11 years old. I am in grade 3 at Dongfang School. My favourite subject is science. We have a nice, big science room on the third floor.
I like playing basketball. Today, I am going to play after school. Do you like basketball, too?
Yours,
Peter

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
