Dear diary,
Yesterday was the Mid-Autumn Day. It was a bad day but also a good day. In the morning, I visited my grandparents and cleaned their house. I rode a bike to the shop at noon, but I fell off my bike and hurt my foot. In the afternoon, my parents cooked a dinner for us. In the evening, our family ate the moon cakes and watched the moon. Then it old them a famous story of Chang’e Flying to the Moon. We were very happy.

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
