Thanks for your letter and the great photos. I like your photos very much. Here are some of my photos. In the first photo, I am swimming in the lake. In the second one, I am playing football in the playground in our school. In the third one, you can see my family at home. We’re having dinner. In the last one, my little sister Beth is watching TV and I am doing my homework. Best wishes to you and your family. Please write to me soon.
Yours,
Jim

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
