It is far, so we are going there by bus. We’ll watch TV together. On Sunday morning. I’m going to the zoo by bike. I will see the monkeys. On Sunday afternoon, I am going to the bookstore to buy an English book. On Sunday evening, I am going to read the English book. I think I’ll have a nice week.

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
