I watched a television programme about China last night. An old lady talked about her life many years ago. She lived in a small house. She cooked on a fire. She didn’t have a television or a radio. She didn’t have a telephone. She worked in the fields. She couldn’t read or write.
I miss my grandma. I miss you, too!
I hope you are well.

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
