Hello, everyone! Do you like playing basketball? There are 40 students in our class. Everyone in the class likes it very much. And many of them are good at it. More than half of my class play basketball every day. We have a boy team and a girl team. In PE classes, the two teams have matches. They play well. But they’re friendly, too. This Friday afternoon, our girl team will play basketball with Class Three. I think we must win.

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
