Most children like watching TV. It’s very interesting. By watching TV, they can learn a lot and know many things about their country and the world. Of course, they can also learn over the radio. But they can learn better and more easily on TV. Why? Because they can hear and see at the same time, but they can’t see anything over the radio.
Watching TV helps to open children’s eyes. Watching TV helps to open their minds(智力), too. They learn new and good ways of doing things. Many children watch TV only on Saturday and Sunday evenings. They are very busy with their lessons on weekdays. But a few children watch TV every night. They go to bed very late, so they can’t have a good rest. How about you, my young friend?

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
