There are some easy things you can do to protect the earth:
•Plant flowers, grass or trees.
•Whenever you visit a park or beach, take away what you take there. Keep rubbish in a bag until you can put it in a dustbin(垃圾桶).
•Turn off the lights and TV set when you leave the room. This can save a lot of electricity.
•Turn off the tap when you brush your teeth. You can save some water by not letting it run.Also, use a glass cup instead of a paper cup because this saves paper.
•Give your old books and magazines to a library instead of throwing them away.
•Give your old clothes to poor children you know instead of throwing them away.
•Use both sides of paper.
•Stop pouring dirty water into the rivers or lakes nearby.
•Encourage all your friends to do the same things you do to help protect the earth.
You don't have to wait until Earth Day to do these things.Make every day Earth Day.If everyone makes a contribution( 贡献) to protecting the environment, the earth will become much more beautiful.

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
