| Hi, Tommy! Thanks for your email. I’m happy to have a friend from the USA. I’m going to show you my photos. Look at the first photo. I’m playing the erhu at my tenth birthday party. My birthday is on Christmas Day. I can have a big dinner with my family. In the second photo, I’m playing ping-pong with Robin. In the third photo, I’m walking on the Great Wall with Robin. Please write soon. Best wishes, Wu Binbin | ||

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
