一带不结心,两股方安髻。惭愧白茅人,月没教星替。海李商隐【杂歌谣辞·李夫人歌】
炉火照天地,红星乱紫烟。赧郎明月夜,歌曲动寒川。李白【秋浦歌十七首】
此马非凡马,房星本是星。向前敲瘦骨,犹自带铜声。李贺【马诗二十三首】

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
