Do you think you can communicate (交流) without words? A smile on your face shows you are happy or friendly. Tears in your eyes tell others that you are sad. When you raise your hand in class, the teacher knows you want to say something or ask questions. You shake your head, and people know you are saying "No". You nod and people know you are saying "Yes".
People can communicate in many other ways. An artist can use his drawings to tell about beautiful mountains, about the blue sea and many other things.
Books can tell you about all the wonderful things in the world and also about people and their ideas. Books, magazines, TV and films all help us to communicate with each other. They all help us to know what is going on in the world and what other people are thinking about.

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
