Dear Oliver,
How are you? I will leave my primary school in China soon. Last Friday, we had a farewell party at school. We drew pictures and sang songs together. We also had a big cake and drank juice. We were very happy. Tomorrow I will go back to the USA with my mother. We are going back by plane. My good friend Mike also likes Chinese very much. He wants to learn it from me. I’m going to teach him over the summer holiday. Tell more about you, please.
Yours
John

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
