只见师傅的手臂悠然(挥来 摆来),悠然(挥去 摆去),如同(跟 伴)着鼓点,随着琴音,每一摆刷,那长长的带浆的毛刷便在墙面“啪”地清脆一响,极是好听。啪啪声里,一道道浆,衔接得天衣无缝,刷过去的墙面,真好比平平整整打开一面雪白的屏障。
1.用“\”划掉括号里不正确的字词。2.这段话描写了
3.这段话先写了刷子李刷墙时的

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
