First, we should have a balanced(平衡)diet.Though we may not like eating vegetables, the vegetables are important. They are very good for our health. Second, we'd better eat regular meals. We need to eat breakfast, lunch, and dinner every day. Because regular(有规律)meals throughout the day can give us enough energy to carry out our daily activities.Third, we should get away from fast food, for it may cause a lot of disease。

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
