Dear Ann,
I hope you're well. I'm on holiday in London with my friend, Lucy. I arrived by plane last Monday. On Tuesday we saw Big Ben and Buckingham Palace. The next day we visited the British Museum and had dinner at a Chinese restaurant. On Thursday we went to Tower Bridge on the River Thames and looked at the city.
Today is Friday. We did some shopping. I took lots of photos and I'm sending them with email to you! Tomorrow we're going to fly home. It was a short holiday, but it was great!
Yours,Amy

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
