What’s your homework? |
Mary, 15 My homework for physics was recycling used batteries (电池)! Tired but happy, I realized there were lots of used batteries polluting our environment. Let’s collect them and save the Earth! |
Tom, 14 I felt so stressed when I cooked noodles for my parents, which was my homework. I guessed it would be difficult for my parents to eat. But to my surprise, they ate the noodles quickly and praised my cooking skills. But actually, the noodles were not quite as delicious as they said. I understand what family love really is. |
Jack, 14 The most interesting homework I’ve done is planting green beans, I planted five seeds in the pot and watered them twice a day. I expected them to grow, so I watched them every day. A week later, they all grew into beans. Learning is like planting. A good result always comes from great care. |
Cathy, 14 We went to some restaurants during the winter vacation to put up posters like “No smoking” and “Don’t waste food” to help people develop good habits. This homework was interesting and helpful. I wish I could do it again. |

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
