(1)将下面的表格补充完整:
列数(n) | 1 | 2 | 3 | 4 | 5 | 6 | … |
苹果树数量/棵 | 1 | 4 | 9 | 25 | 36 | … | |
针叶树数量/棵 | 8 | 16 | 24 | 32 | 48 | … |
(3)当n= 时,苹果树与针叶树的数量相等。

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
