I study many subjects. They’re all very interesting. I like Physics very much, it tells me that why apples fall on the ground (地面). I like Chinese, too. I learn many nice poems. When do we use papers? Do you know? Read this history book about it, please. And you can find the answer. My favourite subject is Science. I know how the spaceship flies into space. What’s your favourite subject?
1．I think some of the subjects are not interesting.2．Chinese tells us something about why apples drop.
3．There’re many poems in Chinese books.
4．My favourite subject is Science.
5．I want to know the spaceships. So I should read Physics books.

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
