省份 | 现存确诊(人) | 治愈(人) | 死亡(人) | 累计确诊(人) |
黑龙江 | 0 | 386 | 0 | 386 |
上海 | 6 | 331 | 0 | 337 |
广东 | ( ) | 181 | 0 | 209 |
北京 | 1 | 173 | 0 | ( ) |
(2)上海输入病例累计确诊比黑龙江少几人?
(3)看到“死亡”人数都为0,你有什么想说的?

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
