How are you? I’m having a wonderful time here in London. I'm meeting lots of people and making lots of new friends.
I was at a great party last Saturday. It was at Peter’s house. It was his birthday. He is eleven years old. There were a lot of people there. The music was beautiful and the food was great. Peter’s mum was a good cook. There were sandwiches, cakes and drinks. We all enjoyed the party.

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
