Hi! I’m Peter! This is the photo of my family.
We had a birthday party for my mother yesterday. Her birthday is in March. My grandpa’s birthday is in May. My grandma’s birthday is in September. My father’s birthday is in summer. It’s on June 27th. And my birthday is in summer, too. It is on Children’s Day. Is it fun?

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
