Long long ago, there was a little mouse. On a sunny morning, the mouse rode a bike to the park. On his way to the park, he met a big cat. He was very afraid of the cat so he rode his bike away. However (然而) , his bike broke. He had to take a bus home. When he got home, he was very hungry. He ate a bowl of noddles and drank a cup of milk. He broke the cup just after drinking the milk. So he had to clean the floor.
When he was cleaning the floor, his grandma came. He was very happy to see his grandma. His grandma cooked a delicious dinner for him. After dinner, they took a long walk in the park.

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
