Ted is a frog of six months old. He lives on an old mushroom, but he doesn’t like it any more. He wants to have a new home. So he leaves home, and he is looking for a new one.
Ted comes to a big tree. He sees a squirrel（松鼠）going to her home in a hole in the trunk. He doesn’t think a tree house is good for him because he can’t climb a tree. Then he finds a hole in the ground under the tree. And an ant is climbing out of his hole. He thinks it’s nice to have a home under the tree. But the ant’s hole is too small for him.
Ted feels tired, so he sits on the grass near a pond. He thinks it is a good place for him. He can jump into the pond and swim in it.
New Ted is sleeping on it, He has a nice dream.

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
