Hi, my name’s Friday. My best friend is Robinson. We live on an island. In the morning we always get up early. We usually look for food. Sometimes I clean my cave. I like spring because in spring I can find lots of food. I’m good at sports. Robinson likes to play sports with me. I often win. Robinson is a little unhappy.

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
