In this photo, we are in the mountains. We are having a picnic. It’s a fine day. The sun is shining and the wind is blowing. The birds are singing in the trees, they sing beautifully. The butterflies are dancing in the flowers. The rabbits are jumping in the grass. The sheep are drinking water by the river. Simon’s father and mother are fishing under a big tree. Simon and I are playing hide-and-seek.
We are having a lovely day.
Love,
Daming

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
