Boys and girls,
Today, I’m very exciting to speak here1.
and I’d like to talk with my grandma. 2.A little months ago, my grandma started to do square dancing 3.
after supper. Since then, she have been in love with square dancing 4.Now she is fitter. But, some neighbours have a complaint(抱怨)5.
against the people which do square dancing. They think that 6.
the music is such loud that they can’t fall asleep at night. 7.
In my opinion, people can’t do square dancing because it is 8.
a good way of keeping health. But they should think about the feelings 9.of other people and they shouldn’t make a lot of noises. 10.
That’s all. Thank you!

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
