What should we do to fight (对抗) NCP? First, we should stay at home and open the windows to keep the air fresh and clean. We should wash hands often. Second, we should eat healthy food, drink a lot of water and do more exercise. We should keep enough (足够的) sleep of eight hours. At last, we had better not go to crowded (拥挤的) places. We are certain (确信) that we can beat (战胜) it.

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
