Once there was a mouse in an old house. He l1． there alone (单独). There was much food for him to eat, and he didn’t like sports (运动), so he was becoming fatter and fatter and he couldn’t run fast.
One day, a black cat came near and she saw the m2．. “It is my food”. The cat said to herself. When the mouse saw the cat, he was very a3． and wanted to run away. But he ran so slowly and the cat caught h4．. “Please let me go. I will give you many good things to eat”. The mouse said. The cat was very h5． hearing the words and she let the mouse go. From then on, the cat got many food to eat and she also became very fat too and she couldn’t run faster than (比) the mouse.

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
