秋天的雨,有一hé五彩缤纷的yán liào。红红的枫叶像一枚枚yóu piào,飘哇飘哇。橘子、柿子你挤我碰,zhēng着要人去摘呢!菊花xiān子得到的颜色就更多了,紫红的、淡黄的、雪白的……美丽的菊花在秋雨里频频点头。秋天的雨,带给大地的是一曲fēng shōu的歌,带给小朋友的是一首欢乐的歌。

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
