It’s Monday today. But we don’t go to school because it’s May Day. It’s sunny and cool. We are in a nature park with Miss White. She is our math teacher. She’s very kind. We all like her. Look! Kate and Lily are running and jumping. Bob is picking flowers with John. Mike is watching a rabbit. It’s eating carrots. Miss White is cooking lunch for us. I’m helping her. I’m washing vegetables.

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
