Dear Helen,
I’m on the farm in America now. Every day it’s sunny and warm. There are a lot
of children on the farm. I work and play games with them. Now I’m writing the letter
in the house. Jack is learning to swim. Terry is lying (躺) in the sun. John is
reading a newspaper and some children are playing football near the house. We are
going to milk cows tomorrow, so we have to get up earlier tomorrow morning.We enjoy
(享受) the holiday very much.
See you soon.
Love,
Janet

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
