It is autumn in April here in Sydney. Autumn is my favourite season! It is warm in the day and cool at night. Many people visit us in autumn because they like the weather.
When you come, you can visit the Sydney Royal Easter Show. It is the largest event in Australia.
What is the weather like in April in your city? What do you often do?
All the best,
Stella

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
