Dear Daming,
Thank you for your letter. I'm in England now. And I have lots of English friends here. They asked me to invite you to come here, too.
Sam likes flying kites. He bought many Chinese kites. Look, there's a photo of him. He's holding a dragon kite. Amy's hobby is collecting Barbie dolls（芭比娃娃）. She has many Barbie dolls.
We are waiting for your coming.
Yours,
Lingling

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
