Catherine is my good friend. She is from the US. She lived in Chicago when she was a little girl. After she grew up, she moved to Cuangzhou. She has blonde (金黄色的) hair and big green eyes. There are four people in her family. Her father is an engineer and her mother stays at home to take care of them. Catherine has a brother. He is a primary school student.
Catherine speaks English, and she can speak Chinese too. We often talk about our favourite books and movies. We know about each other very well. Every Friday, we go to the singing club together. We both like singing very much. After having the singing class, her mother often sends me back home. Sometimes, she can even stay overnight (过夜) at my home. We are like twin sisters.

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
