Dear Amy,
I went to hospital yesterday. I had a cold. But I am better now. This morning I went to Sam’s office(办公室). I met Sam and Tom there. Sam is very busy now. He will be home at seven o’clock. He will have dinner with us. I will make Chinese food for him. He likes Chinese food very much. Do you like Chinese food?
See you tomorrow.
Love from,
Daming

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
