Yesterday my friend and I went to the zoo. We saw many kinds of animals. First, I went to Mammal World. I saw a 1． (tiger / whale) there. It was big, and it had beautiful fur. Then I went to Bird Land. I saw a 2． (parrot / penguin) there. It’s from America. I can talk in English and Chinese.
Then I saw the biggest mammal at the zoo. It was a 3． (shark / whale) in Fish World. The most beautiful animal at the zoo was a blue and yellow flying insect. It was a 4． (penguin / butterfly). My favourite animal was in Reptile World. It was a 5． (snake / bee). It was long and cute.
I liked the trin very much. It was very interesting.

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
