(1)这样宏伟的建筑群,这样和谐统一的布局,不能不令人惊叹。(改为感叹句)
(2)下课时,教室里摆开场子,吸引了一圈黑脑袋,攒着观战,还跺脚拍手,咋咋呼呼,好不热闹。常要等老师进来,才知道已经上课,便一哄作鸟兽散。(仿写表现人入迷的句子)

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
