Thank you for your letter. I’m happy you like the hat.
Everything is fine at the farm. But it’s rainy and cool here, so we can’t go outside. Your friendly and cute dog is here. “Woof! Woof!” Can you hear it? He is playing with me. The animals on the farm are happy, too. There are about forty baby ducks now. “Quack, quack!” They are yellow and funny. There are many baby cows, too. “Moo, moo!” They’re white and black. They are cute. Many vegetables on our farm are fresh. Tomatoes, carrots, green beans, onions, ... The food here is very cheap.
Please write soon, my dear boy! Welcome back! We miss you!
Love,
Grandpa

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
