Life in foreign countries
It is interesting to visit another country, but there are some problems when we don’t know the language very well. It may be difficult to talk to the people there. We may not know how to use the telephone in the country. We may not know how to buy things. In a foreign country, we may not know where to eat and what to order in a restaurant. It is not easy to decide how much to pay for the waiters or taxi drivers. When we need help, we might not know how to ask for help. It’s not pleasant to meet with such problems.

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
