八月涛声吼地来 那声音如同山崩地裂。好像大地都被震得颤动起来
须臾却入海门去 只见白浪翻滚。形成一堵两丈多高的水墙
头高数丈触山回 浪潮越来越近,犹如千万匹白色战马齐头并进:可是余波还在漫天卷地般涌来。
卷起沙堆似雪堆 霎时间。潮头奔腾西去。

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
