Mrs. White lived in a big city and she worked in a bank. She went there by car every morning for twenty years. Then she was forty-five years old, and she said to herself: “I’m fat and weak (柔弱的) now, because I go everywhere by car. I’m going to buy a bike.”
She bought one and after that, she always went to her bank on her bike, and not in her car. Sometimes all the cars stopped at a red light, and she went quickly past them to the forest, because her bike was narrow (狭窄的). Then she was happy.
Yesterday she stopped at a red light, and a man came behind her on another bike. He stopped too and said, “Have the police taken your driving license away, too?”

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
