I’m Lily. I’m writing to invite you to my eleventh birthday party tomorrow, June 3rd. It will begin at 2:00 p.m. All my classmates will come to the party. We are going to sing songs, eat cakes and play games. I think we will have a good time. Would you like to come? My family will be very happy to meet you then.
Yours,
Lily

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
