Thirty years ago, my grandparents were young. They didn't wear glasses. Grandma was beautiful. She was a nurse. Grandpa was thin and tall. He was a teacher. He went to work by bike. He liked playing badminton.
Now they are old. They wear glasses. Grandpa can't ride now. He often goes for a walk with grandma after dinner.

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
