It’s Sunday today. Mike is reading a book in his room. His sister Kate comes in and says, “Hi, Mike! What are you doing now?”
“I am reading a book. What’s up?”
“Mum and Dad are working in the garden. Let’s go to help them, OK?”
“OK.”
Their mother and father are busy in the garden. Mike says to his father, “Let me help you, Dad.”
“Thank you, Mike. We want some water, but it’s too heavy for you.” “We can do it together,” says Kate.
Now Mike and Kate are carrying water, and their mother and father are watering the flowers. They are all 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
