Dear Lingling
I'm having a great time in London! London is a big city. It is in the south of England and it is on the River Thames. Now, I'm staying in a hotel with my friends, Helen and Betty.
It's two o'clock, we are going to visit Buckingham Palace. It's a big and beautiful house. It's the Queen's house. After that, we're going to see Big Ben. I'm going to buy some gifts for you and Sara.
See you next Sunday
Love,
Guoguo

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
