Dear Bill,
I am Lily. I’m 12 years old. And I’m 154 cm. I live in Sydney, Australia. I like swimming and taking pictures. Last weekend I went to the science museum. I went there by bus. I saw many dinosaurs, but they are not real. Last weekend I was very happy. What about you? Write to me.
Lily

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
