Hello, I’m Lulu. It’s Chinese New Year(春节). My family all wear new clothes. Look, my father is wearing a red T-shirt. And my mother is wearing a red skirt. They look nice. Look at my grandpa’s red jacket. It’s great. Look at my grandma’s red dress. How nice! Look at my cap. What colour? Oh, it’s red too. Grandpa says red is for good luck(好运).

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
