Thanks for your letter and the wonderful photos. I like them very much. Here are some of my photos. I'm sending them to you. In the first photo, it is snowing. I'm making a snowman with my friends. In the second one, the sun is shining and the wind is blowing. I'm flying a kite in the park. In the third one, I'm swimming in the sea. In the last one, I'm with my sister Lucy. We're playing chess.
Best wishes to you and your family.
Love,
Jack

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
