Hi, I'm Peter. I was busy last weekend. On Saturday, I read books at home in the morning. After breakfast, I cleaned my room and washed my clothes. In the afternoon, I played football with my friends. In the evening, I helped my mom wash the plates. On Sunday, I visited my grandparents. And I helped them clean their room. I did my homework after dinner. I watched TV at night. How busy I was!

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
