Three students went to London last weekend, and they visited many places. Did they enjoy their trip? Let’s have a look at their diaries.
“It was sunny and warm. I went to London with my friends Emily and James. We visited many places. The guide was very kind and funny. I really had a great time in London!”
—David
“The train was so fast. It only took us half an hour. I read many books about London. When I saw it with my eyes today, I felt so excited! I took many photos. And I also bought some gifts for my sister.”
—Emily
“We went to the science museum. All kinds of model robots are my favorites. I learned a lot about robots. The food in London was kind of expensive, but very delicious. All in all, it was a great trip.”
—James

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
