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